>>> the code once more revealed what the problem was. The syntax errors were occurring in places where there were string constants that contain characters in the upper-ASCII range -- which are often used as "lead-in" characters for double-byte sequences. Essentially what was happening was whenever the character immediately preceding the closing quote was being intepreted as a "lead-in" for a double-byte character, the closing quote would get "eaten" -- thus resulting in the syntax error.

>We side-stepped the problem by using CHR() (rather than entering the string directly with ALT+nnn). For example, wherever we had "©" we simply used CHR(169) instead. And of course, we not only needed to change the PRGs, but also in SCXs, FRXs, DBCs, etc...

Lots of work... although, this being Fox, I assume you wrote some tools to help you there.

Nowadays, I'd probably use varbinary constants. The only reason I'm not using them more is the VFP8 version I still have to maintain here and there, but that should go away soon.
