## Extra Notes

Tried using OpenJDK 25 and 26 using [v0.2.5](https://github.com/GrenderG/openDoJa/releases/tag/v0.2.5) the nightly that is or was available as of a few minutes ago.

Reproduce the menu rendering with DB_RPG_free_3.* and CorpseParty1.* using openDoJa v0.2.5 or the nightly on the reported OpenJDK versions. Compare the unexpected output with the expected Japanese characters and trace the runtime's font decoding and display path. Done means Japanese menu text renders correctly for both games without breaking existing text handling.
