case insensitive Pos

Question

Is there any comparable function like Pos that is not case-sensitive in D2010 (unicode)?

I know I can use Pos(AnsiUpperCase(FindString), AnsiUpperCase(SourceString)) but

Answer 1

I think, converting to upper or lower case before Pos is the best way, but you should try to call AnsiUpperCase/AnsiLowerCase functions as less as possible.
