the mouseText and Unicode

Thanks, Bernd! Using the html is something I didn't try, but otherwise your results are exactly the same as mine: The Russian Robert (Роберт) is the fourth word, yet clicking its first letter reports it as word 3.

Yes, Robert's Chinese ancestor are the culprit here, of course :)

The Chinese characters are displayed whenever you get the bytes wrong, e.g. try to display char 10 to char 11 when the actual double-byte character is char 11 to 12. When all text is non-Roman in a double-byte field, it's easy not to make that mistake (always start with an odd number) , but when some characters are Roman (like that first comma in my example), the mouseCharChunk fails to account for the null byte in front of it, and reports the next character (space) incorrectly. That's my theory at this point... it may be wrong.

The exasperating thing, for me, is that getting word N of a string is not a problem, and neither is locating the position of a word (once you know its characters) . It's identifying the word-position of the mouse-click that is screwed up.

Thanks again... If we ever find a sure-fire way to do this, I'll post the solution here.

Enjoy your weekend,

Slava
