#- strftime returns a string in the locale charset encoding;

#- output of localtime2changelog() is always in UTF-8
#- as to_utf8() uses LC_CTYPE for locale encoding and strftime() uses LC_TIME,
#- it doesn't work if those two variables have values with different
#- encodings; but if a user has a so broken setup we can't do much anyway
