Windows installer is missing Vietnamese as a language option
Vietnamese is one of the TBB packaged languages, but it's not one of the language options in the installer:
- https://github.com/MarkCSmith/tbb-windows-installer/blob/00133b8741eb8ca34fc8153d344c7c54a5e3fae9/torbrowser.nsi#L51 According to http://nsis.sourceforge.net/Examples/Modern%20UI/MultiLanguage.nsi, it should be possible just by adding a line:
!insertmacro MUI_LANGUAGE "Vietnamese"
But Vietnamese probably requires legacy/trac#13469 (moved) to be fixed first, before it will show up in the installer's dropdown list.
