Get the RFC 3066 code for the language of the input data.

The Charset Detection service is intended primarily for detecting charsets, not language. For some, but not all, charsets, a language is identified as a byproduct of the detection process, and that is what is returned by this function.

CAUTION: 1. Language information is not available for input data encoded in all charsets. In particular, no language is identified for UTF-8 input data.

2. Closely related languages may sometimes be confused.

If more accurate language detection is required, a linguistic analysis package should be used.

The storage for the returned name string is owned by the UCharsetMatch, and will remain valid while the UCharsetMatch is valid.

Parameters:

	ucsm	The charset match object.
	status	Any error conditions are reported back in this variable.

Returns:

The RFC 3066 code for the language of the input data, or an empty string if the language could not be determined.
