Problem with mapping a key to multiple characters (Unicode + diacritic symbol)

[Pierre-Luc Angles]

Dear Ilya, dear xorgers,


launching env XMODIFIERS='' GTK_IM_MODULE=xim libreoffice in my terminal 
makes indeed my keyboard for Unicode characters + diacritics working but 
switching to my French keyboard (variant with Sun dead keys), the dead 
keys like the dead_circumflex does not work any more (I have to close 
LibreOffice and reopen it to make env XMODIFIERS='' GTK_IM_MODULE=xim 
libreoffice be ended). I have checked and this is also the case with the 
normal French keyboard azerty.

On the contrary, the dead keys works on the keyboard layout that I have 
mapped when env XMODIFIERS='' GTK_IM_MODULE=xim libreoffice is launched.

It is just a small problem but I would but helpfull to understand why 
some dead keys works and other not when env XMODIFIERS='' 
GTK_IM_MODULE=xim libreoffice is launched.

Thanks again.

Best,

Pierre-Luc
