picked up via XML catalog in freebsd50.ent or xhtml10-freebsd.dtd,

- Define as   in EUC-JP encoding. This is a workaround to
prevent an invalid character in EUC-JP caused by converting 0xa0 in

it should be   still in the final XML output.
- Make XML catalog resolution consistent for l10n.ent. This should be
revisited for the others later.
