$siteLocalesetting in TWiki.cfg - this enables you to have a slightly different spelling of the character set in the server locale (e.g. 'eucjp') and the HTTP header sent to the browser (e.g. 'euc-jp'). This feature should also support use of Mozilla Browser with TWiki:Codev.TWikiOnMainframe (as long as mainframe web server can convert or pass through UTF-8 URLs) - however, this specific combination is not tested. Other browser-server combinations should not have any problems. Please note that use of UTF-8 as the site character set is not yet supported - see Phase 2 of TWiki:Codev.ProposedUTF8SupportForI18N for plans and work to date in this area. This feature is complete in TWiki releases newer than February 2004. Note for skin developers: %INTURLENCODE% is no longer required (TWiki:Plugins.InternationalisingYourSkin). http://www.w3.org/TR/html4/appendix/notes.html#non-ascii-chars The overall plan for UTF-8 support for TWiki is described in two phases in TWiki:/Codev.ProposedUTF8SupportForI18N - this page addresses the first phase, in which UTF-8 is supported for URLs only. UTF-8 URL translation to virtually any character set is supported as of TWiki Release 01 Sep 2004, but full UTF-8 support (e.g. pages in UTF-8) is not supported yet - this will be phase 2. The code automatically detects whether a URL is UTF-8 or not, taking care to avoid over-long and illegal UTF-8 encodings that could introduce TWiki:Codev.MajorSecurityProblemWithIncludeFileProcessing (tested against a comprehensive UTF-8 test file, which IE 5.5 fails quite dangerously, and Opera Browser passes). Any non-ASCII URLs that are not valid UTF-8 are then assumed to be directly URL-encoded as a single-byte or multi-byte character set (as now), e.g. EUC-JP. The main point is that you can use TWiki with international characters in WikiWords without changing your browser setup from the default, and you can also still use TWiki using non-UTF-8 URLs. This works on any Perl version from 5.005_03 onwards and corresponds to Phase 1 of TWiki:Codev.ProposedUTF8SupportForI18N. You can have different users using different URL formats transparently on the same server. UTF-8 URLs are automatically converted to the current
TWiki.cfglocale setting), using modules such as CPAN:Encode if needed. TWiki generates the whole page in the site charset, e.g. ISO-8859-1 or EUC-JP, but the browser dynamically UTF-8 encodes the attachment's URL when it's used. Since Apache serves attachment downloads without TWiki being involved, TWiki's code can't do its UTF-8 decoding trick, so TWiki URL-encodes such URLs in ISO-8859-1 or whatever when generating the page, to bypass this URL encoding, ensuring that the URLs and filenames seen by Apache remain in the site charset. TWiki:Codev.TWikiOnMainframe uses EBCDIC web servers that typically translate their output to ASCII, UTF-8 or ISO-8859-1 (and URLs in the other direction) since there are so few EBCDIC web browsers. Such web servers don't work with even ISO-8859-1 URLs if they are URL encoded, since the automated translation is bypassed for URL-encoded characters. For TWiki on Mainframe, TWiki assumes that the web server will automatically translate UTF-8 URLs into EBCDIC URLs, as long as URL encoding is turned off in TWiki pages. TWiki:Codev.TWikiOnMainframe. Tested with IE 5.5, Opera 7.11 and Mozilla (Firebird 0.7). Opera Browser on the P800 smartphone is working for page viewing but leads to corrupt page names when editing pages.
