Following the post on FuelIndustries, here is my attempt at a complete glyph list for French characters:

<glyphRange name="French Characters " id="26" >
    <range min="0x0020" max ="0x0020" />
    <range min="0x00C0" max ="0x00C0" />
    <range min="0x00C2" max ="0x00C2" />
    <range min="0x00C4" max ="0x00C4" />
    <range min="0x00C6" max ="0x00CB" />
    <range min="0x00CE" max ="0x00CF" />
    <range min="0x00D4" max ="0x00D4" />
    <range min="0x00D6" max ="0x00D6" />
    <range min="0x00D9" max ="0x00D9" />
    <range min="0x00DB" max ="0x00DC" />
    <range min="0x00E0" max ="0x00E0" />
    <range min="0x00E2" max ="0x00E2" />
    <range min="0x00E4" max ="0x00E4" />
    <range min="0x00E6" max ="0x00EB" />
    <range min="0x00EE" max ="0x00EF" />
    <range min="0x00F4" max ="0x00F4" />
    <range min="0x00F6" max ="0x00F6" />
    <range min="0x00F9" max ="0x00F9" />
    <range min="0x00FB" max ="0x00FC" />
    <range min="0x0152" max ="0x0153" />
</glyphRange>

Placing this in the appropriate file (see link above) will allow French characters to be embedded for textfields very simply. I’ll try to do the same with other European languages and post the file here whenever I get time.
