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

Explains and solves a problem with non-ASCII languages.

NSIS does not support Unicode. When you see rubbish characters when you have selected a certain language, you should check the following and correct it if nescessary:

Do you have Windows support for that language installed?

If not, please install the Windows supprort for that language.

Do you have selected that language as the default language for non-Unicode programs?

If not, you can set it in the Regional and Language Options control panel. Click the Advanced tab and look in the Language for non-Unicode programs groupbox.

If this doesn't solve your problem, you should search the NSIS Forum for a solution. If you can't find any (working) solution, you may post your problem at that forum.
