This page contain information about the GNU libc locale collection, including patches, suggested formates, list of known problems and who to contact regarding the different locales. It is a work in progress. The page maintainer, Petter Reinholdtsen, is working with the GNU libc maintainers to get all the fixes included in the official releases of the source.
It is currently an open question where the format og locales in glibc is documented. This list of references is at least pointing to related docuemnts documenting the format of locales, even if the glibc maintainers might not accept them as authoritative.
To make it easier to compare locales with each other, I recommend using the same order in all locales. Any order will do, so I picked a order used in several locales, and decided to recommend this order:
The GNATS database is dead at the moment (2003-10-31), and has been dead since this summer.
If you know of some patches that should be listed here, please send me an email. I want to track all relevant patches, not just the ones submitted by me.
I'm interested in creating a new mailinglist for discussiong the GNU libc locales. It would be a forum where we can discuss how to write locales and how locales should behave, without drowning in the technical discussions about linker problems and syscall conventions. Roland McGrath told me that such list could be created if there is a significant number of people interested in being on such list, and not interested in being on libc-alpha.
The following people have expressed their interest in joining such list. If you are interested in such list, please send me an email.
