(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.

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 for è, Ctrl-Shift-ue9 for é...
  • 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 0 to force unicode, instead of ascii (eg. Alt-0183 to get Middle Dot)
  • 4-digit hex code, then Alt-X — Type unicode character code in hexadecimal, then press Alt-X (at least in Office applications)
