Functions Related to UTF-8
•
0
• A negative number if
Description
The function takes two UTF-8 strings (s0, s1 ) of unsigned char to be compared. The
comparison rules are as follows:
• If both UTF-8 strings are NULL or zero-length, 0 is returned.
• If one of the strings is NULL or zero-length, the NULL/zero-length string is
smaller.
• If one or both of the strings are not UTF-8, system provided
used.
• If one of the two strings contains no 8-bit characters,
• The strings are compared after converted to lower-case UTF-8.
• Each character is compared from the beginning.
Evaluation occurs in this order:
• If the length of one character is shorter then the other, the difference of the two
lengths is returned.
• If the length of the corresponding characters is the same, each byte in the
characters is compared.
• If there is a difference between two bytes, the difference is returned.
• If one string is shorter then the other, the difference is returned.
Do not use this function for collation as there's no notion of locale in this function;
it's UTF-8 code order, which is different from the locale based collation.
