double byte chars

[Slava Paperno]

Have you used 

set caseSensitive to true?

If it doesn't do what you want, you can always compare the decimal character
code points, 1072 for the lower case a, 1040 for the upper case A etc.

I do use "select after" in my fields with Russian/English text to set the
insertion point and have not noticed it being slow, but I have not used it
in a repeat loop, so I don't know the answer to that question.
