EXTERNRT const OSUTF8CHAR* rtxUCSToDynUTF8	(	OSCTXT *	pctxt,
		const OSUNICHAR *	inbuf
	)

This function converts a null-terminated Unicode string into a UTF-8 string.

Memory is allocated for the output string using the built-in memory management functions.

Parameters:

	pctxt	Pointer to context structure.
	inbuf	Null-terminated Unicode string to convert.

Returns:

Converted UTF-8 character string.

EXTERNRT long rtxUCSToUTF8	(	OSCTXT *	pctxt,
		const OSUNICHAR *	inbuf,
		size_t	inlen,
		OSOCTET *	outbuf,
		size_t	outbufsiz
	)

This function converts a Unicode string into a UTF-8 string.

A buffer large enough to hold the converted UTF-8 characters must be provided. A buffer providing 4 bytes-per-character should be large enough to hold the largest possible UTF-8 conversion. The output UTF-8 string is null-terminated.

Parameters:

	pctxt	Pointer to context structure.
	inbuf	Unicode string to convert. Does not need to be null-terminated.
	inlen	Number of characters in inbuf.
	outbuf	Buffer to hold converted string.
	outbufsiz	Size of output buffer.

Returns:

Total number of bytes in converted string or a negative status code if error.
