setLocale() controls the localization aspects of Wt, to adapt strings to a local translation. > Where does the witty application gets the local settings if i do not use > setLocale() ? It gets the locale from the WEnvironment, which in turns fetches it from the browser settings. But most of the time, browsers will report English (even if the user does not speak English natively). You can change the locale using setLocale(). But, the problem you face is not so much a localization issue, but rather an internationalization issue: you want to display text from a non-ascii7 character set. You two choices to make Wt display any unicode character: 1) use WString::fromUTF8() with a UTF8 encoding of the character. For example, the UTF8 representation for Ü is 0xc3 0x9c. 2) use WString::tr() and specify the value in an XML file with e.g. character UTF8 encoding. The benefit is that you can use any XML editor to edit the file without worrying about the encoding: WYSIWYG. The latter has the benefit that it also will open the way to having proper localization perhaps later on for your application, where you make an XML file per language. Wt internally uses UTF8 to represent unicode strings and also communicates using UTF8 with the browser, so unless you have other reasons, UTF8 is a good choice for dealing with unicode characters everywhere. > WString::tr sets my keys in "?? key ??" so it cant get the local > settings. so whats wrong with it? You need to create an XML file which contains values for your keys, and use wApp->messageResourceBundle().use(). Many examples use this method to push strings (or pieces of HTML) to XML files. See for example the homepage, or the simplechat example for how this works. I hope this helps (what will for sure help is unicode support in C++0x !).
