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 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)
