      Description

      How to fix

      You need to create a new Windows username without any special characters, changing your current username DOES NOT work

      Windows 7, 8, 8.1: https://support.microsoft.com/en-us/help/13951/windows-create-user-account#create-user-account=windows
      *NOTE:* Scroll down for Windows 7 instructions, use the Windows 8.1 instructions for Windows 8
      Windows 10: https://support.microsoft.com/en-us/help/4026923/windows-10-create-a-local-user-or-administrator-account

      Description from MC-143300 (CapFan):

      Testing result Summary: Windows userpaths with non-ANSI characters will result in a client crash. This cannot be fixed with --workDir.

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

      Result details: The Test username (English) is in both Ascii and ANSI sets. This was my control to verify that the testing methodology was sound. In both cases, the client ran normally. The Testö username (Swedish) is not ascii, but is in the ANSI set (alt+0246). In both cases, the client ran normally.

      The TestĂ username (Vietnamese) and Testş username (Azerbaijani) are not in the ANSI set. Running with default settings produces the "Could not find or load main class net.minecraft.client.main.Main" error (launcher_log.txt). Running with --workDir C:\MC argument produces the "java.lang.UnsatisfiedLinkError: Failed to locate library: lwjgl.dll" error (crash-2019-01-28_15.04.56-client.txt).
