Bug Report

When launching the installer (v0.5.8 or later), Japanese text in the GUI is displayed as "□□□" (tofu/missing glyphs).
I did some research on my own but couldn't find any relevant information, so I'm opening this issue.

Installer.jar in 0.5.8-alpha (display is broken)

Installer.jar in 0.5.7-alpha (displayed correctly)
