In unit LazUTF8

Encodes the given code point as an UTF-8 sequence of 1 to 4 bytes.

Declaration

pascal

function UnicodeToUTF8Inline(CodePoint: Cardinal; Buf: PChar): Integer

Arguments

`CodePoint`	Unicode character value to convert.
`Buf`	Destination where encoded byte values are stored.

Function result

Number of bytes required for the UTF-8-encoded value.

Description

UnicodeToUTF8Inline is an Integer function used to convert the Unicode character value in CodePoint to the sequence of bytes needed for the UTF-8 encoding. UnicodeToUTF8Inline stores the UTF-8-encoded byte values for the Unicode character in the Buf parameter.

The return value contains the number of bytes required for the UTF-8-encoded value (in the range 1..4).

Used in the implementation of UnicodeToUTF8 and UnicodeToUTF8SkipErrors.

UnicodeToUTF8Inline does not process #0 byte values for the codepoint, as done for UTF-32.

An experiment, built from development snapshots. Not the official Free Pascal or Lazarus documentation.
