Display Unicode character in MFC Static Text - unicode

I am trying to get an MFC Static Text control to display an ASCII Unicode character, specifically Omega (&#937). When i use just that the & doesn't display and the rest of the text does. But if i set the 'No Prefix' Property of the Control to True, then it removes the & and everything after it.
Is this possible to do through a project setting or am i just inputting the string wrong?
Here is what I am using for a string: VDC Resistance (k&#937) → where I want &#937 to be the omega symbol.

First of all &#937 isn't an ASCII character, it is a Unicode character: GREEK CAPITAL LETTER OMEGA.
&#937 is the Html escape sequence for an omega, so a static text control doesn't do translate Html escape sequences. If you are entering the text in C/C++ source then use the C escape sequence L"\u03A9". (3A9 in hex equals 937 decimal). This assumes that you are building a Unicode application in in ANSI it won't work. I'm not sure how you would do it in that case.

Adding the combining overline unicode character

I'm writing a program that converts an integer to a Roman numeral.
Roman numerals over 3999 are overlined, so IV overlined is 4000, CM overlined is 900'000, etc. These lines can stack.
So as to not limit my program, stopping it at just 3999 isn't good enough.
The question is, how do I add the "combining overline" unicode character to my string to achieve this?
My program is written in Rust, but I suspect the solution is similar across most languages that support unicode strings.
Just add the combining mark after each character.
Here's a Python example. What you see depends on support for combining marks in your console/IDE/browser.
with open('test.txt','w',encoding='utf-8-sig') as f:
print('I\u0305V\u0305',file=f)
Output (image and text)
(image) I̅V̅ (text)
In testing, U+0305 COMBINING OVERLINE could stack up to two, but Chrome drew incorrectly for three. There is also U+033F COMBINING DOUBLE OVERLINE.
You can just use them in string constants, either with the Unicode escape sequence (here shown for Rust) or directly (as they can be easily represented in UTF-8 source code files):
println!("I\u{0305}V\u{0305} - I̅V̅");
Note however, that each letter with overline requires two Unicode codepoints. So they do not fit into a single char. You need to use a string.
The combining overline character itself fits into a single character:
let combining_overline = '\u{0305}';
To apply it, insert it after the base character that needs the overline.

How to display cross symbol as superscript with unicode?

I want to display a cross in the place of superscript, I know the unicode character of the cross (\u2020).
Unicode encodes plain text. Superscripting isn’t plain text, so you need something external to, or “on top of” plain text. For example, on a web page, you could use the CSS to position character above the baseline (and reduce font size). In a word processor, you would use superscripting command or style.
In Unicode, there is a limited number of superscript characters, i.e. variants of characters in superscript style encoded as separate characters, such as superscript two “²”. But Unicode has no mechanism for superscripts in general.

What's the ASCII character code for '—'?

I am working on decoding text. I am trying to find the character code for the — character, not to be mistaken for -, in ASCII. I have tried unsuccessfully. Does anybody know how to convert it?
Quotation from wiki (Em dash)
When an actual em dash is unavailable—as in the ASCII character set—a double ("--") or triple hyphen-minus ("---") is used. In Unicode, the em dash is U+2014 (decimal 8212).
Em dash character is not a part of ASCII character set.
— is known as an Em Dash. It's character code is \u2014. It is not an ASCII character, so you cannot decode it with the ASCII character set because it is not in the ASCII character table. You would probably want to use UTF8 instead.
Windows
For Windows on a keyboard with a Numeric keypad:
Use Alt+0150 (en dash), Alt+0151 (em dash), or Alt+8722 (minus sign) using the numeric keypad.
This character does not exist in ASCII, but only in Unicode, usually encoded by UTF-8.
In UTF-8, characters are encoded by 2- or 3-byte sequences (or occasionally longer), where none of the two or three bytes is a valid ASCII code, where all of them are outside the ASCII range of 0 through 127.
One suspects that the foregoing only partly answers your question, but if so then this is probably because your question is, inadvertently, only partly asked. For further details, you can extend your question with more specifics.
The character — is not part of the ASCII set.
But if you are looking to convert it to some other format (like U+hex), you can use this online tool. Put your character into the first green box and click "Convert" (above the box)
further below you'll find a number of different codes, including U+hex:
U+2014
Feel free to edit this answer if the link breaks or leave a comment so I can find a replacement.
Alt + 0151 seems to do the trick—perhaps it doesn't work on all keyboards.
alt-196 - while holding down the 'Alt' key, type 196 on the numeric keypad, then release the 'Alt' key

Is there a name / set for characters that can be typed using a standard english keyboard?

The phrase I think you are looking for is the Latin alphabet, or the ASCII character set.

Japanese ASCII Code

Where can I get a list of ASCII codes corresponding to Japanese kanji, hiragana and katakana characters. I am doing a java function and Javascript which determines wether it is a Japanese character. What is its range in the ASCII code?
ASCII stands for American Standard Code for Information Interchange, only includes 128 characters (not all of them even printable), and is based on the needs of American use circa 1960. It includes nothing related to any Japanese characters.
I believe you want the Unicode code points for some characters, which you can lookup in the charts provided by unicode.org.
Please see my similar question regarding Kanji/Kana characters. As #coobird mentions it may be tricky to decide what range you want to check against since many Kanji overlap with Chinese characters.
In short, the Unicode ranges for hiragana and katakana are:
Hiragana: Unicode: 3040-309F
Katakana: Unicode: 30A0–30FF
If you find this answer useful please upvote #coobird's answer to my question as well.
がんばって!
Well it has been a while, but here's a link to tables of hiragana, katakana, kanji etc and their Unicodes...
http://www.rikai.com/library/kanjitables/kanji_codes.unicode.shtml
BUT, as you probably know Unicodes are hexadecimal. You can translate them into decimal numbers using Windows Calc in programmer mode and then input that number as an ASCII code and it will produce the character you want, well depending on what you're putting it into. It will in MS Wordpad and Word(not Notepad).
For example the hiragana ぁ is 3041 in Unicode. 3041 is hexadecimal and translates to 12353 in decimal. If you enter 12353 as an ASCII code into Wordpad or Word i.e hold Alt, enter 12353 on the number-pad then release Alt, it will print ぁ. The range of Japanese characters seems to be Hiragana:3040 - 309f(12352-12447 in ASCII), Katakana:30a0 - 30ff(12448-12543 in ASCII), Kanji: 4e00-4DB5(19968-19893 ASCII), so there are several ranges. There's also a half-width katakana range on that chart.
Japanese characters won't be in the ASCII range, they'll be in Unicode. What do you want, just the char value for each character?
I won't rehash the ASCII part. Just have a look at the Unicode Code Charts.
Kanji will have a Unicode "Script" property of Hani, hiragana will have a "Script" property of Hira, and katakana have a "Script" property of Kana. In Java, you can determine the "Script" property of a character using the Character.UnicodeScript class: http://docs.oracle.com/javase/7/docs/api/java/lang/Character.UnicodeScript.html I don't know if you can determine a character's "Script" property in Javascript.
Of course, most kanji are characters that are also used in Chinese; given a character like 猫, it is impossible to tell whether it's being used as a Chinese character or a Japanese character.
I think what you mean by ASCII code for Japanese is the SBCS (Single Byte Character Set) equivalent in Japanese. For Japanese you only have a MBCS (Multi-Byte Character Sets) that has a combination of single byte character and multibyte characters. So for a Japanese text file saved in MBCS you have non-Japanese characters (english letters and numbers and common non-alphanumeric characters) saved as one byte and Japanese characters saved as two bytes.
Assuming that you are not referring to UNICODE which is a uniform DBCS (Double Byte Character Set) where each character is exactly two bytes. Actually to be more correct lately UNICODE also has multiple DBCS because the character set could not accomodate other character anymore. Some UNICODE character consiste of 4 bytes already having the first two bytes as leading character.
If you are referring to The first one (MBCS) that and not UNICODE then there are a lot of Japanese character set like Shift-JIS (the more popular one). So I suggest that you search Shift-JIS character map. Although there are other Japanese character set map aside from Shift-JIS.
