How do I write unicode, in hexadecimal, to Facebook "What's on your mind" box?
I have tried writing:
\u00B9
"\u00B9"
¹
"¹"
none worked so far
(let me add that I am doing this from a MAC)
thanks
I feel that facebook converts it all to human-readable string. I think that isn't possible
Try Alt+0185 on the keyboard if you are using Windows, it should have the desired output for you.
The examples in the lead are HTML entities. They would need to be ended with a semicolon, but no matter, they do not work in a Facebook comment. The answer supplied was not, the original poster said that he was using a Mac, not Windows, so the ALT- method does not apply. I know that I did once enter Greek characters, as I was talking about stars in constellations with Greek designations like α Vir, but I don't recall how to do that now and the UNICODE universe may have been usurped by Facebook's stupid emoticon universe.
On Mac OS X, if you do not wish to use the Character Viewer, you can set your preferences to allow input of Unicode characters by code like in Windows.

I am trying to intercept and replace emoji with a corresponding text. I left the default encoding on the Web API (UTF-8 / UTF-16 respectively).
How can I convert an emoji like 😉 to something like U+1F609?
Here is something that helped me out, although it is in Perl. But you can encode and decode. This should be what you're looking for: https://metacpan.org/pod/Encode::JP::Emoji
This is quite an old post and even though I'm not on the project anymore I want to still answer with my findings for future reference if someone else has the same problem.
What I ended up doing is to create a dictionary with key the UTF combination of the emoji and as a value the text. One thing as an advice: I made sure the longest UTF combination, some emoji have 4 or even 5, as the first ones as otherwise some emoji never got reached. Totally not a perfect and future proof solution that I was hoping for but it worked for us and it shipped into production where it has been working since 2017.
I am working with the Distributions package which uses special unicode characters for many of the variables within types. The normal distribution, for instance, uses μ and σ. If I want to edit the standard deviation, I need to somehow type:
n.σ = 5.0
Is it possible to type these values into the repl (outside of using copy-paste)? How does one create these characters with one's keyboard?
Thank you
At the REPL, use LaTeX shortcuts, e.g. type \sigma and press tab to autocomplete. Note you need to using Julia 0.3 or higher for this to work.
Many text editors have add-ins to do something similar, e.g. https://github.com/mvoidex/UnicodeMath for SublimeText.
In Windows 10 and Linux under most modern desktops you can add a Greek keyboard map and then switch between Greek and English using [[windows button]]+space. Since many Latin / English letters are derived from ancient Greek, these have analogs so S types a Sigma (σΣ), D, a delta(δΔ) etc. ετψ.
Figured it out by looking up "Entering Unicode in Linux" on Google.
One can press Ctrl+Shift+u, then the 4-digit UTF-16 Hex encoding for the character. For example, σ = u03bc
Tt is difficult to remember all the unicodes or latex shortcuts (at least for me) or search it on the web. When working with REPL or jupyter notebook, Julia has provided a simple way to do it as mentioned here:
You can also get information on how to type a symbol by entering it in the REPL help, i.e. by typing ? and then entering the symbol in the REPL (e.g., by copy-paste from somewhere you saw the symbol).
For example:
I am trying to get some of the more abstract math symbols and utilize them in Adobe Fireworks with limited success. I use the character map feature of windows and cut and paste. It does not work for most symbols. Is there another option?

This Adobe forum seems to suggest changing your font to Arial Unicode MS:

For myself, Character Map seems to work reliably, although I am using "FontAwesome", not mathematical symbols.
You can also try directly typing the character code using Alt + [type numerical code of font].
Hope this helps!
There are a lot of programmers editors that claim to support unicode / utf-8. I've tried a number of them (UltraEdit, jedit, emedit) but none of them tell you how to actually enter unicode characters into a file. Some of them tell you how to change the default file encoding to utf-8 or how to select a font that has good support for utf-8, but not how to enter utf-8 into a file using their editor.
The Go language (and some others) support utf-8 and I like the idea of using the actual utf-8 symbols for variables instead of variables with names like omega. I haven't found a programmers editor yet that actually allows you to do this, though.
The only editor / word processor that I've found that lets you how to enter unicode is Microsoft Word. Type the unicode and Alt+X and Word converts it. To get the Greek letter omega type "03c9" followed by Alt+X. UltraEdit will let you copy utf-8 from a web page into it, but their docs don't say how to actually enter utf-8 in a file, and their tech. support people don't know either.
This should be simple, but seems to be completely undocumented. Is there some key combination convention the lets you enter unicode into these editors that supposedly support unicode the way that Ctrl-F is widely used for search?
Thanks.
The standard programmer’s editor vim(1) supports limited Unicode input even if your operating system should be too broken to do so (are there any such, still?).
Just enter ^VuXXXX, where XXXX represents exactly four hex digits.
That will allow you to enter the ~6% of Unicode allocated to the Basic Multilingual Plane. The rest are forbidden to you.
This may be fixed in a newer release.
Otherwise, just use your mouse.
A few techniques I use if an editor is lacking:
Use the Windows charmap.exe utility to select characters and paste into a document.
Install an input method editor (IME) to write in a particular language.
Windows ALT keycodes.
Better to set your keyboard to generate Unicode characters across all Windows applications than to rely on a single application's custom input feature IMO.
Use the EnableHexNumpad feature and you can type any character in the Basic Multilingual Plane using Alt+numbad-plus,hexcode. (May not be of much use on a laptop without a numpad though.)
Or if there are particular characters you want to type a lot, find a keyboard layout that allows you to type them directly. For example eurokb might cover it, or you can make your own with MSKLC.
Old question, but you can type a lot of unicode in GNU Emacs or Vim
GNU Emacs: M-x set-input-method RET tex (or C-x RET C-\ tex) will let you type \omega to generate ω
Vim: Vim digraphs can generate unicode; C-k w * in insert mode gives you ω.
deceze hit the nail on the head. (S)he just didn't elaborate. bobince gave a bit more.
And I'm hazarding a guess that you're a developer or tester working on L14N or I18N. I'm also guessing you need to do more than just a few characters here or there, or you'd be satisfied with pasting from another app. So, I'll share some advice. (note: here, "you" refers to the next person to look here. I'm sure the original poster doesn't care anymore by now. :-))
If you're on Windows 10, install an appropriate keyboard driver that lets you input the characters you want into any application. I'm sure Linux has support for the same sort of thing.
E.g. I'm teaching myself Hindi (हिंदी), so I installed Windows' Hindi (Devanangari) support. I typed "Hindi", in Hindi using that support, then I switched back to US English to do the rest of this post. If all you need are accented characters from Western European languages, you can install the INTL English support and type directly in español or français or whatever.
Don't look at entering Unicode characters as entering some sort of special data amidst your English text. It's just someone else's language. Use their keyboard. Type their language.
I'm writing a flashcard app to help my learning. I'm using the Hindi keyboard support to type characters into Word, WordPad, Excel, and the Visual Studio editor. And that Hindi keyboard support works exactly the same way in all of those apps, as I'd expect it to work in just about any text editor that supports Unicode. And as you saw above, it also works in a simple text edit control in Chrome. No copy and paste. No remembering special codes. It's as ubiquitous as ctrl-F.
It looks like the unicode support in programmers editors (except for some Microsoft products) is mostly read-only. They can open a file with unicode and display the characters, but typing unicode into a file is a different story. If you want to enter unicode in a programmers editor you can copy it from somewhere else (a web page or Microsoft Word or Notepad) and paste it into the editor, but the editors make typing unicode difficult or impossible.
UltraEdit tech support referred me to this web page which explains a lot. Unfortunately none of the solutions worked with UltraEdit.
Microsoft Word and Notepad support unicode entry. Type the unicode value followed by Alt+X and it converts the hexadecimal and displays it. You can then copy and paste it into UltraEdit or one of the other programmers editors. As others have mentioned unicode support depends on support within the operating system as well as the editor.
What got me interested in using unicode in source code files is Mark Summerfield's book Programming in Go. He includes an example .go file that uses unicode. It would be great to use unicode Greek characters for variable names instead of variables named "omega" or "theta".
Using unicode in source code is a bad idea, however. Support for unicode in programmers editors is lousy, and developers would have to save or convert their source code files to utf-8 instead of ASCII. Developer's tools are just not ready to write code in unicode no matter how neat the idea sounds.
Can scalaz be used without a keyboard containing the appropriate Unicode characters or does every Unicode identifier also have an "ASCII" equivalent (and if yes, is there any guarantee that it stays that way)? Are there special keyboard layouts for usage with scalaz?
What's the best practice? Inputting the Unicode identifiers directly or using the ASCII substitutes and using a script to replace them with the Unicode ones before commit?
No, you don't need anything besides ASCII to use Scalaz.
However, most editors and IDEs have some way of automatically or semi-automatically (like, -space) converting a sequence of characters into something else. That takes care of it if you want to keep your source code in Unicode.
Now, the problem with keeping stuff in Unicode is that you might trouble with some fonts when displaying stuff in web pages, etc. Hell, you might even be forced to convert the code to ASCII for some reason. Yes, it is unlikely, but it is an issue you should be aware of.
This post from Superuser has some information about this.
This wikipedia article on Unicode input might be helpful.
No. Yes. Yes. No. Benign guarantees are for sissies. Write code. I use an appropriate development environment that allows me to type whatever I like.
