That won't work, Victor, since it makes invalid encoding
names valid, e.g. 'utf(=)-8'.

We really only want to add the functionality of matching
encodings names with hyphen or not.

Perhaps it's not really worth the trouble as Alexander suggests
and we should simply add the few extra cases where needed.
