Declaration

Source position: lazutf8.pas line 134

function UTF8LowerCaseFast(

const AText: string

):string;

Arguments

AText

String with the content examined and converted to its lowercase representation.

Function result

Lowercase value for the specified text.

Description

UTF8LowerCaseFast examines the ordinal values for the characters in AText to determine how the return value is derived. It is optimized for ASCII content (byte values in the range 1..128). It converts individual characters in the range ['A'..'Z'] by adding 32 to their ordinal values.

If a non-ASCII byte value is found in AText, the return value is derived by calling UTF8LowerCase with the value in AText as an argument.
