Par contre, je n'arrive pas à faire CTRL+MAJ+U+Codes



Ca m'écrit le U ou ambiguité de raccourci !!!

Heu... Ecrire "je t'aime" ?...

The possibility of hexadecimal code input on operating systems using the X Window System depends on the system and applications. Hex input is not implemented in the common X.Org Server.[6] Individual input methods and GUI toolkits can provide hex input independent of the X server.



For example, GTK+ is an ISO 14755-conformant system. The beginning sequence is Ctrl+⇧ Shift+U and the ending sequence is ↵ Enter or Space. Programs based on GTK+, such as GNOME applications, support Unicode input.



There are two common methods for direct input of Unicode characters:



Hold Ctrl+⇧ Shift and type u followed by the four hex digits. Then release Ctrl+⇧ Shift.

Enter Ctrl+⇧ Shift+u, release, then type the four hex digits, and press ↵ Enter (or Space or even on some systems, press and release ⇧ Shift or Ctrl ).

In OpenOffice.org and Inkscape, for example, only the second method works.



In non-GTK applications, however, there usually is no escape sequence to input arbitrary input characters. For example, Qt, KDE rely on the standard X Input Method (XIM) framework, and do not implement their own solutions.[7] In xterm, these input methods are not be supported, but using escape sequences is an alternative.



However, regardless of the toolkit used, the Compose key subsystem can be used to configure certain key stroke combinations to input a subset of unicode.



In platform independent applications



In Emacs, Ctrl+x8↵ Enter or Meta+x ucs-insert.

In Opera (browser) versions, that use the Presto layout engine - i.e. up to and including version 12.xx -, enter the hexadecimal number of the desired symbol or character and then press Ctrl+⇧ Shift+x (alternative shortcut Meta+⇧ Shift+x on OS X).

In the Vim editor, in insert mode, the user first types Ctrl+V u, then types in the hexadecimal number of the symbol or character desired, and it will be converted into the symbol. (On Microsoft Windows, Ctrl+Q may be required instead of Ctrl+V.[8])

The capability of Vim to create custom mnemonics, as described below, which could be employed on an ad-hoc basis, requires the decimal code point.

Il y a deux façons courantes de saisir un caractère unicode :



* Maintenir Ctrl+⇧ Maj et taper u suivi des quatre chiffres hexa. Puis relâcher Ctrl+⇧ Maj.

* Faire Ctrl +⇧ Maj+u, relâcher, puis taper les quatre chiffres hexa, et presser ↵ Entrée (ou Espace et même sur certains systèmes, presser et relâcher ⇧ Maj ou Ctrl ).



Dans OpenOffice ou Inscape, par exemple, seule la seconde méthode fonctionne.
