Malformed UTF-8 tolerated in single-quoted strings

Isn't this a bug?

    % blead -CS -le 'print qq(print "\xB0C";)' 
    print "°C";

    % blead -CS -le 'print qq(print \x27\xB0C\x27;)'
    print '°C';

    % blead -C0 -le 'print qq(print "\xB0C";)' | blead -Mutf8 -CS -l
    Malformed UTF-8 character (unexpected continuation byte 0xb0, with no preceding start byte) at - line 1.
    C

    % blead -C0 -le 'print qq(print \x27\xB0C\x27;)' | blead -Mutf8 -CS -l
    #C

That is, it correctly detects the bad UTF-8 when 
it's in double quotes, but not when it's in single ones.

Isn't this an error?
