Subject: * encoding.c (rb_enc_mbclen): return minlen instead of 1 when   a
 character is not found properly.

* string.c (rb_enc_strlen): round up string length with fixed
  multibyte encoding such as UTF-32.
  (rb_enc_strlen_cr): ditto.
  (rb_str_substr): fix substring with fixed multibyte encoding.
  (rb_str_justify): check number of characters.
