(LaTeX symbol name from package unicode-math)
How to find Unicode symbols:
- shapecatcher.com - unicode character recognition — draw the symbol with the mouse to find it!
- In Gnome, see character maps (
gucharmap) to get unicode hex code. - In KDE, try KDE Character Selector (
KCharSelect). - In Windows, try Character Map. Use Search for field to search characters with matching description (click Advanced view)
Using Combining symbols:
- In Windows, try Character Map. Use Search for with Combining to find all combining symbols.
- Use a unicode fonts to get best results
- In Office, Word and Visio seems to give good results. Powerpoint sometimes misaligns the symbols.
- Tip: Type the letter, then type a space and move cursor back, then type the combining diacritic [1]
Reference:
- unicode-math package (see unimath-symbols.pdf, also in LaTeX documentation)
- Mathematical operators and symbols in Unicode (on wikipedia) (with explanation links for lots of symbols!)
Tips
- Inserting Unicode symbols in Linux
These are similar to Windows' Alt-key code.
- Ctrl-Shift-u, followed by unicode hexadecimal code while maintaining Ctrl-Shift (see [2])
- Ex Ctrl-Shift-ue7 for
ç, Ctrl-Shift-ue8 forè, Ctrl-Shift-ue9 foré...
- In Gnome, see character maps (
gucharmap) to get unicode hex coce. - In KDE, try KDE Character Selector (
KCharSelect).
- Inserting Unicode symbols in Windows
- Alt-KP0-Alt-KP9 — Press Alt key then the unicode character code in decimal.
- For small code, prefix fix
0to force unicode, instead of ascii (eg. Alt-0183 to get Middle Dot)
- For small code, prefix fix
4-digit hex code, then Alt-X — Type unicode character code in hexadecimal, then press Alt-X (at least in Office applications)
Unicode fonts
Some fonts with good unicode support.
On Windows:
- Arial MS Unicode
- Cambria Math
All platforms:
- sil.org (see Gentium)
