Help+Manual's project files are always encoded in Unicode, which means that you can develop help projects in all languages, including Asian languages and other languages with more than 255 characters that are supported under Windows. The only restriction is on right-to-left languages like Arabic, Farsi and Hebrew. You can edit projects in RTL languages, but you can only publish to HTML Help CHM and WebHelp. Other output formats are not supported for RTL languages.
When you are working with languages requiring Unicode and some other languages requiring special characters, including Eastern European languages, Greek and Turkish, it is important to configure your project correctly to avoid problems in your published help files.
In addition to this there are also some important requirements for your Windows configuration for Unicode-based languages, and you need to be aware of these before you start work on a project in a language requiring Unicode.
The topics in this chapter provide some useful background information on handling international languages that should make these issues easier to understand.
