# xfig-wrapper is a little shell script, which tries to work around the
# missing UTF-8 capabilities of xfig.
# For this it allows to use the content of environment variable XFIG_LC_CTYPE
# as LC_CTYPE.  If this is not set, it checks whether you use a UTF-8 locale.
# If this is the case, it tries to strip UTF-8 from the locale and checks,
# whether the result is defined.
