I have unusual characters showing up in the lyrics

If you have unusual characters in the lyrics displayed by KaraFun Player, especially with your own files (.mid, .kar etc), the character set used by the software might be the issue.

In order to change that:

1. Open Windows Registry Editor
2. Navigate to HKEY_CURRENT_USER\Software\Recisio\KaraFunPlayer2
3. Find "CodePage" entry, and change it to whatever code suits your file (see below)

In most situations, 65001 will work, but if you need a specific character set, you can find a list of character sets and their associated code here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd317756%28v=vs.85%29.aspx
