Unicode has a million icon-like glyphs, but they're not always easy to search by, since I don't always know what they look like.
Is there a Unicode glyph that looks like a "key"? Or is there a symbol that's used in database circles to mean "primary key", which is in Unicode?
U+1F511 π KEY
(128273 decimal)
Also:
U+1F5DD π (Decimal: π) OLD KEY
U+26BF βΏ SQUARED KEY
U+1F510 π CLOSED LOCK WITH KEY
U+1F512 π LOCK
U+1F513 π OPEN LOCK
U+1F50F π LOCK WITH INK PEN
To find useful symbols, I have this resource:
http://shapecatcher.com
Allows you to draw a shape, which it then searches for similarly shaped unicode symbols.
I often end up using shapecatcher these days just because it's a fun break just to be able to draw the shape that you want and have the site pull it up for you. At least, sometimes it will pull it up.
Misc. Symbols Blocks
http://shapecatcher.com/unicode/block/Miscellaneous_Symbols_And_Pictographs is also a great category of unicode symbols, though as with all unicode, you may have to test compatibility.
This is duplicated from my answer here because I think the approach will be useful to others besides just me: What Unicode character do you use in your website? (instead of image icons)
I used a little Python 3 script to look, and the closest I found does not display here for me (does display in Idle on my machine), but it is:
9897 β© HORIZONTAL MALE WITH STROKE SIGN
(Looks like a male sign pointed right with a perpendicular stroke added between the arrow and circle)
I searched for various matches like "KEY" and "LOCK" in the unicode names using Python's unicodedata module and no luck there.
Editing to add - Ah hah - one that looks even more like a key:
9911 β· CHIRON
I give both of the above code points in decimal. To see them and their hex codes, go to this link:
http://www.unicode.org/charts/PDF/U2600.pdf
See 26B7 in particular for the Chiron.
Check out #26bf.
9919 βΏ SQUARED KEY (HTML: βΏ)
It's the parental lock, which is a key inside a square. It's a newer Unicode specification so standard fonts don't support it, but if you can find a font that has it, you're home free.
I've found Google to be the best way to find Unicode characters. I didn't find see anything useful for a key symbol, however.
If you want to search visually, use the PDF charts, since HTML-based listings will only show symbols that occur in the particular set of fonts you have installed.
Lacking any specific symbol, I would just use "I" to indicate an index and "PK" for a primary key.
I browsed through all the symbols (using a PHP script I created a while back) and can't see a key symbol. You could try one of these:
A mathematic-looking P:
β (#8473)
Various star shapes:
β
(#9733)
β (#9734)
βΆ (#10038)
There doesn't seem to be a unicode character that fits your description, but I'd recommend the silk icon set by famfamfam if you can use icons in your situation--just a suggestion :P

Is there an unicode symbol for "n/a"? There are some fractions like Β½, but a n/a symbol seems to be missing.
If there is none, what would be the most appropriate unicode symbol to use for n/a in a website (which should be contained in common fonts, to avoid needing a webfont)?
Looking at the Unicode code charts, I do not see a single N/A symbol. I do, however, see βΏ (U+207F) and β (U+2090), which you could separate with / (U+002F) eg: βΏ/β, or Μ· (U+0337), eg: βΏΜ·β, or ΜΈ (U+0338), eg: βΏΜΈβ. Probably not what you are hoping for, though. And I don't know if "common" fonts implement them, either.
For future reference, the fastest way I know to answer questions like the OP's when I have them myself is to go to unicodelookup.com, because of the way it works: there's a search bar at the top, and you just type a string and it will return any and all unicode characters containing that string (this is also a great way to discover new and useful symbols). So in the OP's case, he could proceed like this:
first try entering "not" (without the quotes) in the search field
visually scan through the results... doing so would not reveal a "not
applicable" character in this case
try again but this time entering "applic" in the search field
again, doing so would not turn up anything along the lines of what he's
looking for
At that point he would be reasonably confident the current Unicode standard does not have a "n/a" symbol.
If you use Firefox you can define a keyword like "uni" to search that site from the URL bar, meaning any time the browser is open and regardless of what page or site is currently showing, you could do this:
hit [F6]... this moves the cursor to the URL bar at the top
type something like "uni applic" and hit [Enter]... this brings up the
unicodelookup.com website with the search results for "applic" already
showing
For the above to work you would need to define your keyword ("uni" or wtv you prefer) to point to location http://unicodelookup.com/#%s.
There's a Negative Acknowlege icon...
β symbol for negative acknowledge 022025 9237 0x2415 β
Found by searching negative on the Unicode Lookup site.
I'm not a fan, and for my purposes have just gone with __N/A__ (Markdown..)
I see lots of answers going head-on at the "Not Applicable" abbreviation, without exploring what a symbol is. A quick search for the equivalent phrase "out of scope" brings up a couple of variations on the No symbol: β β this seems to fit the bill (and since I was looking for a way to represent inapplicability, I'll be using it in my technical document).
Per the Wikipedia article, the Unicode codepoint U+20E0 is a combining character, so it is superimposed on the preceding character; e.g. ! β overlays an exclamation point. To get it to appear isolated, use a non-breaking space
If you don't want to bother with the combining symbol, the article mentions there's also an emoji U+1F6AB π« but it's typically going to be colored red, or won't render!
There's actually a single character that could be repurposed for this: the "Square Na" character γ (U+3381), which is used to represent the nanoampere in fullwidth (CJK) scripts.
What about the "SYMBOL FOR NULL" β (U+2400)?

I want to know , how can we convert a font to Unicode font. I have PDF file in my native language but those text has been written in a specific font file (ttf file). So i want to convert those text into Unicode fonts.
So how can i convert those text into Unicode. Is there any free online software available or i have to write any software code in any language.
I have tried in PHP but not getting much more effective.
Your question mixes several basic concepts (it is unclear whether you want to convert a font or the text it's written with), and I suggest you look a bit deeper into font technology before asking "then so how would I do it".
"Normal" fonts are using Unicode encoding. The "encoding" of a font describes which character image inside a font gets output for a given character code. A font can contain several encodings -- MacRoman, Windows Western -- and nowadays including a Unicode encoding is practically standard.
A font that does not comply to Unicode encoding (or any of the common ones) cannot be used without a translation from its character set to Unicode.
Your description suggests that the font in your PDF may be such a non-conforming font, so you need a table that maps its character codes to Unicode values. Use Google to see if someone else did this before you; if not, you will have to create the table yourself.
However.
Since your text comes out of a PDF, you cannot rely anymore on the encoding! If a PDF gets created, the software that does it is free to move characters around to different positions -- usually it creates a subset font from the original, and it can be convenient to reassign character codes. Friendly PDF creators may also include their own encoding in the PDF, but it is not mandatory. If it is missing, and your font is subsetted, then there is only one solution: you will have to create a translation table for that particular PDF. It will not be of any use for other documents using "the same" font, because that most likely will have a different subset.

I saw this two symbol and i copied it.
try to do any html entities or special character.. but i can't get any result
I can't find any information on google also because this is not a searchable symbols
any one can explain how this flat and sharp musical symbol exist in which standard?
and how to type or generate them and any siblings?

The standard used to define the characters is Unicode
See Unicode Miscellaneous Symbols (includes common music symbols like β―) and Unicode Musical Symbols (other music symbols) -- I did a search for "unicode musical symbols", there are many more hits.
Happy coding.
See How to enter Unicode characters in Microsoft Windows -- or use the Windows Character Map. However, you need to know the code-point (or general code-point area)
:-) Other operating systems have different input methods and utilities.
A quick google search find the following page which lists entity codes for musical notes:
http://www.danshort.com/HTMLentities/index.php?w=music
It is in Unicode, and you can insert any Unicode character by putting this in HTML/xHTML markup:
β¬
Gives β¬, i.e. you put &#x and suffix it with the Hex code of the character (end it with ;)
P.S: This technique is used as the last resort when facing character encoding problems.

Unicode
and how to type or generate them and any siblings?
There are utilities for picking characters from unicode distributed with most operating systems.
I am looking for an online service (or collection of images) that can return an image for any unicode code point.
Unicode.org does not have an image for each one, consider for example
http://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=31cf
EDIT: I need to use these images programmatically, so the code chart PDFs provided at unicode.org are not useful.
The images in the PDF are copyrighted, so there are legal issues around extracting them. (I am not a lawyer.) I suspect that those legal issues prevent a simple solution from being provided, unless someone wants to go to the trouble of drawing all of those images. It might happen, but seems unlikely.
Your best bet is to download a selection of fonts that collectively cover the entire range of characters, and display the characters using those fonts. There are two difficulties with this approach: combining characters and invisible characters.
The combining characters can easily be detected from the Unicode database, and you can supply a base character (such as NBSP) to use for displaying them. (There is a special code point intended for this purpose, but I can't find it at the moment.)
Invisible characters could be displayed with a dotted square box containing the abbreviation for the character. Those you may have to locate manually and construct the necessary abbreviations. I am not aware of any shortcuts for that.

I'm looking for a good character that means "end-of-story" in unicode. I remember seeing one once that looked like a fractal and was really cool. Does anyone know where I can find this character? More importantly, where can I go to find a unicode character with a special meaning when I don't know it's names? Google wasn't very helpful.
Edit: I found something that looks kinda like a fractal, and also happens to be called "end-of-story." It's a Thai character.
Is this what you were looking for?
http://www.decodeunicode.org/en/u+0e5b/data/k//XS/khomut31910809.jpg
End of story The Khomut sign is a terminal punctuation character which is placed in old books at the end of a verse in a poem, the end of a chapter or at the end of a story.
Compare to U+17DA Khmer Sign Koomuut
Btw: I found this with a Google Image Search on "end of story" unicode--It was the 4th result. That's probably the best way to search for any kind of symbol. Though without the name of the character it would probably have been impossible to find, since unicode fractal didn't return anything useful.
Go and have a look at the unicode.org code charts. You can browse through them and find a character that you like by what they look like. http://www.unicode.org/charts/
Alternatively, browse through the names of the characters using the data file that has the official character name. Do a search using your browser or editor search function. http://www.unicode.org/Public/5.1.0/ucd/UnicodeData.txt
When you find a character that you want to see what it looks like, just do a search for the character code. e.g. character 0087 (the first field in the UnicodeData.txt file) is searched as U+0087. FileFormat.info usually has all of the characters. For example, END OF SELECTED AREA.
Are you using Windows? Use the Character Map (Start | Accessories | System Tools). I personally like the Greek Omega (U+03A9) or the Ohm sign which is an Omega (U+2126).
