Does your minecraft use turkish locale? Is your modded minecraft crashing? If you answered yes to both questions this mod might fix your problem. Usage of the mod is simple: download mod and install it to mods folder. Then start your game and crash should be gone. WARNING: this mod fixes only small subset of crashes: please see examples.

It is possible to accomplish same result without mod

add -Duser-language=en as an extra java argument or
wait launcher developers fix launcher(s) to include that argument by default.

For pack makers it might be easier to use a mod which injects fix automatically.
