Yeah, if we don't want to skip such files, then storing them using
a base64-encoded name (with a different key than regular names)
seems plausible. But I don't really see why we'd go to that much
trouble, nor why we'd think it's likely that tools would correctly
handle a case that is going to have 0.00% usage in the field.
I mean, I gave a not-totally-unrealistic example of how this could
happen upthread. I agree it's going to be rare, but it's not usually
OK to decide that if a user does something a little unusual,
not-obviously-related features subtly break.
Another example might be log files under pg_log with localized weekday
or month names. (Maybe we're not planning to back up log files, but the
routines that deal with file names should probably be prepared to at
least look at the name and decide that they don't care about it rather
than freaking out right away.)
I'm not fond of the base64 idea btw., because it seems to sort of
penalize using non-ASCII characters by making the result completely not
human readable. Something along the lines of MIME would be better in
that way. There are existing solutions to storing data with metadata
around it.
