Utf8FromBuffer - cCharTranslate

Creates a UTF-8 string in a memory buffer from an OEM or ANSI memory buffer

Type: Function
Return Data Type: Pointer

Parameters

Parameter Type Description
pMultiCharBuffer Pointer The address of a null terminated string
eCharType Integer The type of string encoding, which may be OEM (CP_OEMCP), ANSI (CP_ACP) or UTF-8 (CP_UTF8)

Syntax

Function Utf8FromBuffer Pointer pMultiCharBuffer Integer eCharType Returns Pointer

Call Example

Get Utf8FromBuffer pMultiCharBuffer eCharType to PointerVariable

Description

Utf8FromBuffer creates a UTF-8 string in a memory buffer from an OEM or ANSI memory buffer.

The length of the returned UTF-8 string may be obtained using CStringLength(). This returns the number of bytes in the string, which may not be the same as the number of characters in the string.

You are responsible for eventually disposing of the newly created memory buffer. This may be accomplished by using the Free function.

Use Windows.pkg
Use cCharTranslate.pkg
