​Ok, back after my second morning coffee :)

A better way to check for Chinese code points would be
something like that (not tested and never used myself) :


function testForChinese utf8Text
   return matchText( utf8Text, "\p{Han}")
end testForChinese

Of course, it won't work with  htmlText, but straight with
the text of a field, assuming it's coded in UTF8 !!!


HTH,

Thierry
