[Setup]: ShowUndisplayableLanguages

Valid values:

Default value:

no
Description:

By default, languages that cannot be displayed on a user's system due to a code page mismatch are not listed in the Select Language dialog. For example, Russian text can only be displayed properly if the active code page is 1251; if the user isn't running code page 1251 they will not see Russian as an option.

If this directive is set to yes, all languages will be listed in the Select Language dialog. To avoid user confusion, it is not recommended that you enable this in production installs.

This directive is ignored by Unicode Inno Setup.
