This issue affects Touhou 11 as well. The offending commit appears to be 65956ae50a136fe8467a0332c7495f36617a16dc, reverting it makes the text render correctly.
I am unable to replicate this (specifically the music room portion) on 4.12.1 for Touhou 11 (I tested both English and Japanese).
However, if reverting the commit fixes Touhou 14-17, then it is likely the cause, though I cannot test it myself.
Could you also submit test data for Touhou 11 on the AppDB, or describe the environment that you tested here? That might be potentially helpful.
On that note, I'm using macOS High Sierra 10.13.6, and I'm running the 64 bit distribution of Wine from https://dl.winehq.org/wine-builds/macosx/download.html
