You need to use a legacy codepage for internal encoding. UTF-8 is not a 
codepage, it's an encoding. The internal encoding stuff (it should be 
called --internal-codepage but that's too late now) relies on an 8-bit 
legacy codepage that can hold the characters you need to process. So 
there wasn't any bug but I now changed that error output to be more 
specific.

$ ../run/john -stdout --mask=?L --internal-encoding=utf8
Can't use ?L placeholder without using a codepage in --internal-encoding
(UTF-8 is not a codepage).

$ ../run/john -stdout --mask=?L --internal-encoding=cp737
