Yes, but chances are that you have asked the wrong question. The function is named unicode2native(), and in the case of translating to US-ASCII, what it mostly does is convert any character outside the range decimal 0 through decimal 127 in to the value decimal 26 (intended to signify that US-ASCII has no way of representing the corresponding character.)

ASCII is really a pretty restricted set of values. The question does get interesting, though, if you do not restrict yourself to US-ASCII and start wanting to do things like translate the "national currency symbol" of UK-ASCII vs US-ASCII vs the symbols used in the Scandinavian languages...

The MATLAB character set represented by the 'char' data type is NOT ASCII. It is not completely documented as to what it _is_, but it it holds values from 0 to 65535, a 16 bit representation, but the mapping from values to character set appears to be left up to preferences or system variables rather than being fixed. It is _not_ UTF-16.
