I have noticed that Google Toolbox for Mac replaces several SQLite built-in functions (LOWER/UPPER, LIKE, GLOB) with its own versions that handle string locales better.

So, question to everyone who has SQLite experience: have you ever had any problems with non-English locales in SQLite? Does one really have to do something to properly handle non-English alphabets? What kinds of problems are expected if I use SQLite APIs as-is?

(I'm going to use SQLite on the iPhone, but I guess it's the same across all platforms. I've been using Core Data previously and never had any problems, but this time I want to switch to non-ORMed db access.)
