My mon is Cambodia-Chinese and usually she will send me some texts in Khmer,
(when she dunno how to express herself in Chinese or English),
But,
here is some example since I installed tons of khmer font for Mac,

and,
this is the result I see,

...
quite awful,
although I can't read it and literally just copy it and paste to "Google Translate",
so,

I would like to ask that,
is there any way,
to change the custom font like, khmer or sth other else.

Postscript,
im quite new to the GIthub and "coding" stuff,
if yes there it is,
please,
treat me like a newbie and don't be hesitate to tell me in more and more simplicity please.
