Radialix 2 relies on Unicode to work with text. The user can edit and create localized files almost in any language, including those that use double-byte character sets (Chinese, Japanese).

The languages supported by Radialix 2 are listed on the Languages tab (Tools > Options>Languages). The current version does not provide an opportunity to add new languages.

On the Languages tab, you can change font and size. Other language attributes can be used as tags in names of files and catalogs.
