首先设定compose键：
Menu System -> Preferences -> Keyboard
（系统－》首选项－》键盘）中文的不知对不对，我现在不用中文的locale，凭记忆写的。
Layout Options: Compose key position:
(随便选一个吧，输入时用的。)
输入方法：
1. Compose key (就刚才定义的那个键，按下后释放)
2. " (按下后释放)
3. i (按下后释放)
要输入 é : Compose, ', e
要输入 è : Compose,`, e
要输入 ç : Compose, ,, c
要输入 œ : Compose, o, e
要输入 ø (not French but can be useful) : Compose, /, o
要输入 ¡ : Compose, !, !
要输入 ê : Compose, >, e
要输入 ě (difficult) : Compose, <, e
以此类推.....
Some other combinations are also useful : (一些其它的绑定：)
« : <, <
» : >, >
€ : =, e
¥ : =, y
ů : *, u
å : *, a
ķ : ,, k
(r) : O, R
× : x, x
÷ : -, :
± : +, -
ñ : ~, n
在其他桌面环境(如xubuntu)下如果没有设置compose键的选项可以这样设置（gnome也可以）：
代码： 全选
gksu gedit /etc/X11/xorg.conf代码： 全选
Option "XkbOptions" "compose:caps" 然后重启xserver
原文：
Whithout a French keybord, it is possible !
Menu System -> Preferences -> Keyboard (Système -> Préférences -> Clavier)
Tab/Onglet : Options de l'agencement
Compose Key position : chose for example Right Ctrl is compose, or
Menu is compose (menu is the special Key between Right Alt and Right
Ctrl to have related Menu under Ms Windows)
Since then, to have, for example, an ï, type
1. Compose key (and release it)
2. " (and release)
3. i (and release)
To have é : Compose, ', e
to have è : `, e
to have ç : Compose, ,, c
to have œ : Compose, o, e
To have ø (not French but can be useful) : Compose, /, o
To have ¡ : Compose, !, !
To have ê : Compose, >, e
To have ě (difficult) : Compose, <, e
Etc.
That is like a spaghetti plate. Difficult to know it all...
Otherwise you can execute charmap and copy/paste characters.
Bon courage pour apprendre le français !
