According to Jack Woehr on 7/29/2008 10:28 PM:
| Can anyone point me to any GNU m4 documentation having to do with
| EBCDIC support or lack thereof?
The manual doesn't really state much on this matter. Most of m4's
processing is byte based (so no multibyte characters), and m4 uses
<ctype.h> to distinguish between the various character types (so it should
generally be EBCDIC safe). The only exceptions I know of is that using a
range operator (such as 'a-z' as the second or third argument to translit,
or '[a-z]' as the regular expression in regexp or patsubst) will probably
work incorrectly, since those are not contiguous bytes in EBCDIC; spell
out the range yourself. A few of the tests in the testsuite will probably
fail because they assume ASCII or Latin-1 encoding.
I don't have access to an EBCDIC system (and these days, they are quite
rare), but if you encounter any bugs, feel free to report them.
