Thank you for confirming this.
In the meantime I tracked down the exact problem. The standards for a
locale name are 'language_country.encoding', as in 'en_GB.utf8' or
'English_United Kingdom.1252'. In Windows XP (at least) Microsoft gives
'Chinese_Hong Kong S.A.R..950'. This is ambiguous, and in at least two
places it was parsed as an encoding of 'A.R..950'. There seem to be only
three locales with dots in the country name (Hong Kong, Macau, U.A.E.), so
it perhaps not surprising that this has gone undetected for so long.
