Create Deco Crashes because of my Turkish local.

createdeco:block/palettes/windows/\u0131ron_window_end

"I" becomes "ı" instead of "i"

Crash log:

fixed for 2.0.2

Until the root cause is fixed, you can add -Duser.country=US -Duser.language=en to your java arguments as a workaround.
This sets Java's locale to English, preventing the error from arising.
