1743 | Returns the Unicode code point of the first character in the string C<s> | |
1744 | which is assumed to be in UTF-8 encoding; C<retlen> will be set to the | |
1745 | length, in bytes, of that character. | |
1746 | ||
1747 | Some, but not all, UTF-8 malformations are detected, and in fact, some | |
1748 | malformed input could cause reading beyond the end of the input buffer, which | |
1749 | is one reason why this function is deprecated. The other is that only in | |
1750 | extremely limited circumstances should the Unicode versus native code point be | |
1751 | of any interest to you. See L</utf8_to_uvuni_buf> for alternatives. | |
1752 | ||
1753 | If C<s> points to one of the detected malformations, and UTF8 warnings are | |
1754 | enabled, zero is returned and C<*retlen> is set (if C<retlen> doesn't point to | |
1755 | NULL) to -1. If those warnings are off, the computed value if well-defined (or | |
1756 | the Unicode REPLACEMENT CHARACTER, if not) is silently returned, and C<*retlen> | |
1757 | is set (if C<retlen> isn't NULL) so that (S<C<s> + C<*retlen>>) is the | |
1758 | next possible position in C<s> that could begin a non-malformed character. | |
1759 | See L</utf8n_to_uvchr> for details on when the REPLACEMENT CHARACTER is returned. | |
