Steve,

Sorry, "static text" is not right. What I meant was that if you need to perform more
complicated comparisons on the text (substring matches, as in a LIKE SQL statement),
the overhead involved in UTF-8 can be significant (20 or 30% slower than with UCS-2).

If it is a simple "yes or no" match on the text, it is not so bad. And of course, UTF-8
sure beats ISO 2022.

Regards,
Jake
