behaviours dealing with codeset name normalization. That is to say that use
of UTF-8, and it's variations, are normalized to utf8. Likewise that values
after the @ are not normalized and left as-is. The test needs to run
localedef with known input values and then check that the generated path
matches the expected value after normalization. */
