There is a comment for UTF8CompareText in LazUTF8 which is contradictorily:
// Returns: < 0 if S1 < S2, 0 if S1 = S2, > 0 if S2 > S1.But S1 < S2 is the same as S2 > S1.
In the first case the result should be < 0 and in the second one > 0.
It cannot even be retrieved from the code how it realy works (unless you are fit in assembler). So when will the result be positive and when negative?
It should be >0 if S1 > S2. I changed the comment.

Under Linux it does not use Assembler.
Internally it uses UTF8CompareStr, which uses CompareMemRange, which returns -1 if a byte of S1 is lower than S2.
I added the comment.

Thanks.
