_ doesn't render inside \text

Do you mean to say that, everything in a text group should be strictly normal text? As in, escape characters, underscores should come as they are.

[ForNeVeR]

I think that \text{\_} should render an underscore. For now I have absolutely no way to render an underscore inside of \text.

Maybe you could include a Unicode command(\uni) which works only if the text style is "text" ,the next non-whitespace character is plus. After the plus sign and the hexcode, there should be a whitespace to signal the end of the code. Try to convert the hex code to an integer and convert the integer to a character. Return a character atom based on the converted character if the character is less than thppthe maximum value of an unsigned short. I believe that would work, along with the other code points that aren't on a standard keyboard. So if that's done, \uni+5f should return an underscore.

Note: Supporting arbitrary codepoints would need you to look out for Combining Marks and Variation Sequences.

Any kind of "Unicode" command looks like a separate feature, please file another issue about that. Also we'd need to find out if any standard LaTeX distribution already supports that kind of command.

[B3zaleel]

They can't support all the possible kinds of commands, that's why we can define new commands to do new things. Although there is the "\DeclareUnicodeCharacter{code point}{\name}" in XeLatex,it's obvious to see why that is inconvenient(especially if you are going to use the command once).

[ForNeVeR]

Yes, we can define new commands if we feel that our users will use WPF-Math's TeX dialect in some uncommon ways (e.g. we could add transparency support etc.). Although, I can't yet see the issue you're trying to solve with your "Unicode" command.

[B3zaleel]

TeX has the command \char{character code in decimal notation}. Which can be used if one needs a special symbol that hasn't been defined.

[Happypig375]

The \char command takes a Glyph Index, not a codepoint.. It is used for where some glyphs cannot otherwise be obtained. However, with your unicode command, it will be very easy to get a codepoint without a corresponding glyph in the current font. How will you deal with that?

A side note: \text{_} should just work without any kind of magic commands: http://www.texpaste.com/n/twxhpxfl
