Depends on what you do with the returned value. Lazarus uses UTF-8 by
default, thus the constant would be in UTF-8 as well and Pos() takes two
AnsiString parameters, thus CP_ACP. So the constant is passed along as is
and s is converted to UTF-8. Depending on the encoding of the characters
you might get a different position, thus you should ensure that both of
your strings have the same type (not tested) or you should work simply in
UTF-8 and only convert for input/output purposes.

Sven
