#1. Why are you using nativeCharToNum instead of codePointToNum ?
Presumably (?) your field "Contents" contains Chinese text.
I am assuming that the codePointToNum of your "0" is 48.
It would help in a big way if you could post "char 22" here.

When I do this sort of thing:
set the htmlText of fld "htmlF" to numToCodePoint(48)
the field shows a "0"
set the htmlText of fld "htmlF" to the text of fld "textF"
produces exactly the same result.

I really wonder what this "�" is?
