Locale::PO now preserves unrecognized flags, although there is still

Browse Source 
no documented way to access them.  It also preserves the order of
flags, if no flags are modified.
  Replaced the fuzzy, c_format, and php_format fields with _flaghash,
and renamed the _flag field to _flagstr.
  Flag-setting functions silently map unsupported values (e.g. 42) to
supported ones (e.g. 1), which they also return.
  The c_format and php_format methods treat empty strings as undef,
rather than as 0.
  Names of flags are case-sensitive, like in GNU Gettext.

If you C<load_file> then C<save_file>, the output file may have slight
cosmetic differences from the input file (an extra blank line here or there).
The C<c_format> and C<php_format> methods are documented: "1 implies
c-format, 0 implies no-c-format, and blank or undefined implies
neither." However, the implementation seems to treat empty strings
the same as 0.
Locale::PO discards the "#," flags it does not recognize.
Unrecognized flags should be preserved; perhaps the order of flags
should also be preserved.
Names of flags are case-insensitive in Locale::PO but case-sensitive
in GNU Gettext.
The C<quote> and C<dequote> methods assume Perl knows the encoding
of the string. If it doesn't, they'll treat each 0x5C byte as a
backslash even if it's actually part of a multibyte character.
