Running with -workDir C:\MC argument produces the ": Failed to locate library: lwjgl.dll" error (crash-_15.04.56-client.txt). Running with default settings produces the "Could not find or load main class .Main" error (launcher_log.txt). The TestĂ username (Vietnamese) and Testş username (Azerbaijani) are not in the ANSI set. The Testö username (Swedish) is not ascii, but is in the ANSI set (alt+0246). This was my control to verify that the testing methodology was sound. Result details: The Test username (English) is in both Ascii and ANSI sets.

Methodology: With each account I attempted to run Minecraft normally, and run Minecraft with -workDir directed to C:\MC_Root\. Setup: I created four administrator accounts, Test, Testö, TestĂ, and Testş.
