UTF8CompareText

Case-insensitive comparison of two UTF-8-encoded values.

Declaration

Source position: lazutf8.pas line 185

function UTF8CompareText(

const S1: string;

const S2: string

):PtrInt;

Arguments

`S1`		First value for the comparison.
`S2`		Second value for the comparison.

Function result

Relative order for the compared values.

Description

UTF8CompareText is a function used to perform a case-insensitive comparison between the specified UTF-8-encoded values. The return value indicates the relative sort order for the compared values, and includes:

0: Values are the same
< 0: Value S1 comes before S2 in an alphabetic sort order
> 0: Value S1 comes after S2 in an alphabetic sort order

Internally, UTF8CompareText uses WideCompareText when multi-byte codepoints are found in the compared values. This function guarantees proper collation on all supported platforms.
