Hi, Tux Mason wrote, The truth is, I don't know. The reason locale support still exist in 1.0 branch, is that I want to be fully backward-compatible to uClibc-git feature set. I actually want to get rid of locale support. I am using uClibc based embedded systems since more than 10 years, but have gotten never a use case for it. So may be I will rethinking about the removal, if you come up with a good reason. Why you want to use locale support? The locale support in GNU libc and musl is better. best regards Waldemar
