openssl egg is tripping on utf8, someplace

[sethalves]

When using read-byte on a port returned from the openssl egg, if a byte with a high bit set arrives, something goes wrong.

See:

​http://paste.lisp.org/display/134012#1

The second paste outputs:

(61 62 63 1fffef 1fffbf 1fffa0 31 32 33)

rather than the expected:

(61 62 63 ef bf a0 31 32 33)

I haven't tested this, but try the attached patch if you can. The issue appears to be a sign error; C_make_character effectively expects int (or an unsigned char). If passed a regular char with high bit set, that's a negative value, which is sign-extended when converted to int and then treated as unicode.

Reported to work by sethalves on IRC. I'll leave this open for about a week and commit it if Thomas does not get a chance.

Fixed in 1.6.2.
