(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.
- TBC
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 [1])
- 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.
4-digit hex code, then Alt-X — Type unicode character code in hexadecimal, then press Alt-X (at least in Office applications)
