They all work for me: type, cat, less.  The file is UTF-8 with BOM. 
Error messages are printed correctly displaying all the characters in a 
buggy symbol.

But now I remember.  It fails to execute any  batch files when it's in 
65001 codepage.  More precisely, it executes exactly one line from a 
batch file like if there were no more lines.  So this pseudo-uniclde 
mode is useless.
