# characters via m4_translit must deal with the fact that m4_translit does

# In EBCDIC, $ is immediately followed by *, which leads to problems
# if m4_cr_all is inlined into a macro definition; so swap them.

# It is mainly useful in generating inverted character range maps, for use
# in places where m4_translit is faster than an equivalent m4_bpatsubst;
