# any 8 bit data (even in comments).  UTF-8 is only a guess here, but it
# will at least accept any 8 bit data.

# The parameter "--language=perl" is not strictly needed because the
# source language of all our files will be auto-detected by xgettext
# by their filename extension.  You should even avoid this parameter
# if you want to extract strings from multiple source languages.
