no joy with fonts

I'm sorry, I've been rather preoccupied and had intended to reply to 
this yesterday.

I have extensive experience with non-Latin scripts in Livecode.

I hope & trust that ALL your fields are Unicode fields . . .

2 years ago, when I embarked on a similar "adventure" to yours I tried 
setting fields to
fonts such as 'Times Ext Roman' and had Livecode playing "merry hell" 
with my settings.

1. Unless you dive into Unicode this problem will persist.

2. You DO NOT need to set the language at all in a Unicode field.

    set the useUnicode of fld "BlahBlahBlah" to true
    set the textFont of fld "BlahBlahBlah" to "Times Ext Roman"

at which point the characteristics of your textFld should stay 
consistent and not do "funny things" such as you describe.

Your students can either enter text directly (i.e. typing into the 
field), or by some more
rococco way such as via a virtual on-screen keyboard that consists of 
buttons/images containing code such as this:

set the unicodeText of fld "BlahBlahBlah" to the unicodeText of fld 
"BlahBlahBlah" & numToChar(XXXXX)

where 'XXXXX' is the Unicode address of, say, the Chinese Glyph you require.
