Before it is considered a duplicate, I make this question, are the methods for showing the text the same? Remember that touhou 10 and up depend on d3dx9_36.dll that is why I think about the possibilty that the methods for rendering text would be different.
Yep, all the Touhou games (maybe sans IaMP/SWR/HSTS) require a functional DIB engine for text rendering, which means both bug 15146 and the infamous bug 421 need to be fixed before the text is completely fixed.
One more thing, Wine's version of d3dx9_36.dll is now functional enough to run Touhou games, so you should see no difference in game operation if you use a native or built-in version of the dll. On top of that, it's not used for text rendering anyway.
