  By default, TWiki is configured to support US ASCII letters (no accents) in WikiWords, and ISO-8859-1 (Western European) characters in page contents. If that's OK for you, skip this step.

If your Wiki will be used by non-English speakers, TWiki can be configured for Internationalisation ('I' followed by 18 letters, then 'N', or I18N). Specifically, TWiki will support suitable accented characters in WikiWords (as well as languages such as Japanese or Chinese in which WikiWords do not apply), and to support virtually any character set in the contents of pages. NOTE: TWiki does not currently support UTF-8, so you are advised not to use this - however, improved UTF-8 support is under development.

  To configure internationalisation suppport:
  1. Edit the TWiki.cfg file's Internationalisation section to set the $useLocale parameter to 1. TWiki will now use the I18N parameters set in the rest of this section.
  2. Type the Unix/Linux command locale -a to find a suitable 'locale' for your use of TWiki. A locale that includes a dot followed by a character set is recommended, e.g. pl_PL.ISO-8859-2 for Poland. Consult your system administrator if you are not sure which locale to use.
  3. In TWiki.cfg, set the $siteLocale parameter to your chosen locale, e.g. pl_PL.ISO-8859-2 for Poland.
  4. Check your setup using testenv (download the latest testenv from TWiki:Support/SupportGuidelines if possible) - this provides some diagnostics for I18N setup, and in particular checks that your locale can be used successfully.

  1. If you are using Internet Explorer or Opera, configure your browser to not send URLs encoded with UTF-8
    • Internet Explorer 5.0 or higher: in Tools | Options | Advanced, uncheck 'always send URLs as UTF-8', then close all IE windows and restart IE.
    • Opera 6.x or higher: in Preferences | Network | International Web Addresses, uncheck 'encode all addresses with UTF-8'.
    • NOTE: If this configuration change is not acceptable, consider installing a TWiki beta release (19 Jan 2004 or later), which fully supports UTF-8 URLs.

  1. (For upgrade of TWiki I18N sites only:) If you were using TWiki:Codev.TWikiRelease01Feb2003 support for I18N, and are using Internet Explorer or Opera, you should re-configure your browser so that it sends URLs encoded with UTF-8 (supported since TWiki:Codev.TWikiRelease01Sep2004). If you are doing a new installation of TWiki, you can ignore this step - no browser reconfiguration is needed for TWiki Release 01-Sep-2004).
    • Internet Explorer 5.0 or higher: in Tools | Options | Advanced, check 'always send URLs as UTF-8', then close all IE windows and restart IE.
    • Opera 6.x or higher: in Preferences | Network | International Web Addresses, check 'encode all addresses with UTF-8'.
    • NOTE: This does not mean that TWiki supports UTF-8 as a site character set.
 
  1. Try out your TWiki by creating pages in the Sandbox web that use international characters in WikiWords and checking that searching, WebIndex, Ref-By and other features are working OK.

Trouble with I18N?

 If international characters in WikiWords do not seem to work, and you are on Perl 5.6 or higher, you may need to set the TWiki.cfg parameter $localeRegexes to 0 - this disables some features but enables TWiki to work even if your system has locales that do not work. Then, set the $upperNational and $lowerNational parameters to the valid upper and lower case accented letters for your locale.

  • NOTE: You will need to do the above workaround for Windows based servers (whether using Cygwin or ActiveState Perl), since Perl locales are not working on Windows as of Feb 2004.

  If international characters in WikiWords aren't working, and you are on Perl 5.005 with working locales, keep $useLocale set to 1 and set $localeRegexes to 0, then set $upperNational and $lowerNational - if testenv generates the lists of characters for you, your locales are working so there is no need to set $localeRegexes to 0 in this case. See the comments in TWiki.cfg for more information.
