The number of bytes escaped will be returned in the C parameter if it is not null. When the C parameter is null no escaping actually occurs, but the number of bytes that would be escaped were it not null will be calculated. If flags contains C then any double quotes in the string will also be escaped. Normally the SV will be cleared before the escaped string is prepared, but when C is set this will not occur. If C is set then the input string is treated as UTF-8 if C is set then the input string is scanned using C to determine if it is UTF-8. If C is set then all input chars will be output using C<\x01F1> style escapes, otherwise if C is set, only non-ASCII chars will be escaped using this style; otherwise, only chars above 255 will be so escaped; other non printable chars will use octal or common escaped patterns like C<\n>. Otherwise, if C then all chars below 255 will be treated as printable and will be output as literals. If C is set then only the first char of the string will be escaped, regardless of max. If the output is to be in hex, then it will be returned as a plain hex sequence. Thus the output will either be a single char, an octal escape sequence, a special escape like C<\n> or a hex value. If C is set then the escape char used will be a C<"%"> and not a C<"\\">. This is because regexes very often contain backslashed sequences, whereas C<"%"> is not a particularly common character in patterns.
