Adding a new language, Vietnamese

Hi bros,

I’m trying to make LanguageTool to support my mother language-Vietnamese.I did the following steps


I just want to build Standard-alone for Desktop. So I ignore some steps. When I start Desktop app, Vietnamese did not appear
.
Is there anybody can tell me what’s wrong and how to solve?

Thanks all,
