We only enable 8-bit output for known single-byte locales, currently ISO8859-*. For all other locales the program output is unchanged. RFC-1288 recommends that administrators have a mechanism to enable characters greater than ASCII 126. A suggested solution is an environment variable. The environment variables of choice here are LC_CTYPE and LANG. Thanks to Martin Husemann <martin@duskware.de> for the idea on checking for known single-byte locales, to Johan Danielsson <joda@pdc.kth.se> for checking RFC-1288, and to Jun-ichiro itojun Hagino <itojun@iijlab.net> for insisting on retaining security for multi-byte locales. If you experience any problems with these changes, please send me email describing the problem and how to repeat it. I'd rather try to fix the problem than have this change reverted. Thanks!
