But perhaps the documentation should indicate that:
the byte strings for zone names will be used, as is, in OS calls to create files, and we don't guarantee what effect that will have (for example, on at least one UNIX(R), with the default file system - regardless of whether it's running case-sensitive or case-insensitive - some amount of processing is done on file names to convert them to UTF-16 on disk);
the byte strings for abbreviations will be copied over to the file, without interpretation;
and that you use non-ASCII characters at your own risk.
