- * Modified by Wei-Hwa Huang, Google Inc., on 2004-09-24
- * This is a slower but "safe" version of the old chartorune
- * that works on strings that are not necessarily null-terminated.
- *
- * If you know for sure that your string is null-terminated,
- * chartorune will be a bit faster.
- *
- * It is guaranteed not to attempt to access "length"
- * past the incoming pointer.  This is to avoid
- * possible access violations.  If the string appears to be
- * well-formed but incomplete (i.e., to get the whole Rune
- * we'd need to read past str+length) then we'll set the Rune
- * to Bad and return 0.
- *
- * Note that if we have decoding problems for other
- * reasons, we return 1 instead of 0.
