Thread: How strings are sorted by LC_COLLATE specifically?
Hello Dear All. How strings are sorted when LC_COLLATE = ja_JP.UTF-8. I tried to read the documention on that,but there are just a few words, like LC_COLLATE determines string sort order, Is there a specific reference about this? So I can implement an equivalent string sort function in JAVA. because some of the sort logic is here. Any clue will be greatly appreciated. Charles

The actual string comparison is done by the strcoll() function in the operating system's C library.
Hi Peter. When I looked into the source(),came to know that strings are sorted like this. int result = strcoll(a, b); if (result == 0) { result = strcmp(a,b); } return result; On Wed, Dec 1, 2010 at 4:31 AM, Peter Eisentraut <peter_e@gmx.net> wrote: > On tor, 2010-11-25 at 14:42 +0900, Chang Chao wrote: >> How strings are sorted when LC_COLLATE = ja_JP.UTF-8. >> I tried to read the documention on that,but there are just a few >> words, >> like LC_COLLATE determines string sort order, >> Is there a specific reference about this? >> So I can implement an equivalent string sort function in JAVA. >> because some of the sort logic is here. > > The actual string comparison is done by the strcoll() function in the > operating system's C library. > >
