don't contain any NUL bytes. This avoids subtle bugs caused by
silently using only the part of the filename until the first NUL byte.
+** New coding-systems for EBCDIC variants.
+New coding-systems 'ibm256', 'ibm273', 'ibm274', 'ibm277', 'ibm278',
+'ibm280', 'ibm281', 'ibm284', 'ibm285', 'ibm290', 'ibm297'. These are
+variants of the EBCDIC encoding tailored to some European and Japanese
+locales. They are also available as aliases 'ebcdic-cp-*' (e.g.,
+'ebcdic-cp-fi' for the Finnish variant 'ibm278'), and 'cp2xx' (e.g.,
+'cp278' for 'ibm278'). There are also new charsets 'ibm2xx' to
+support these coding-systems.
