`P1`	PChar type with UTF-8 codepoints compared in the method.
`P2`	PChar type with UTF-8 codepoints compared in the method.

Function result

numeric difference between differing codepoints, or zero when the same.

Description

CompareUTF8Sequences is an Integer class function used to compare the UTF-8 codepoints in the values specified by P1 and P2. The return value is the numeric difference between the byte values in the differing UTF-8 codepoints. The return value is 0 (zero) when P1 and P2 have the same UTF-8-encoded content.
