It's all rubbish when I use a non-ASCII language

Author: virtlink (talk, contrib)

Issue

When using a non-ASCII language with NSIS, the characters are shown incorrectly.

Cause

NSIS uses MBCS and does not support Unicode languages (FR #1238132).

Solution

Check that you have installed the Windows support for that language, and check that the specified language is the default language for non-Unicode programs. You can check or set it in the Regional and Language Options control panel. Click the Advanced tab and look in the Language for non-Unicode programs groupbox.

A Unicode-compatible version of NSIS is currently under development and its code changes under evaluation for inclusion for a future release. Fore more information, see: Unicode NSIS
