# This file is used via the maint.mk-using rule in Makefile.

# This is a gnulib-specific rule to keep non-ascii characters
# from creeping into our .texi files.  There is nothing inherently
# wrong with e.g., UTF-8 characters in texinfo sources, but here,
# we had accumulated some non-ascii apostrophes and hyphens, and
# they were recently replaced with their ascii analogs.  This rule
# should help keep things consistent.
