Copy the already-decoded Unicode text carried by a

Category	Text decoding

Purpose — Copy the already-decoded Unicode text carried by a TPDFStack (as filled by pdfGetPageText) into a caller-supplied wide buffer.

Description — A pure buffer-copy helper — no font or document involved; it just NUL-safely copies Stack.Text up to Size-1 characters.

Declarations

int32_t __stdcall fntTranslateString(TPDFStack* Stack, const wchar_t* Buffer, uint32_t Size, uint32_t Flags);

Delphi

function fntTranslateString(var Stack: TPDFStack; Buffer: PWideChar; Size, Flags: Cardinal): Integer; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`Stack`	`TPDFStack*`	A stack previously filled by `pdfGetPageText`.
`Buffer`	`PWideChar`	Destination buffer.
`Size`	`Cardinal`	Buffer capacity in characters (including the NUL terminator).
`Flags`	`Cardinal`	Accepted for ABI compatibility; not read by this implementation.

Return value — Number of characters copied (excluding the NUL terminator); 0 if Stack.Text/Buffer is NULL or Size is 0.
