97Escapes at most the first "count" chars of pv and puts the results into
ab3bbdeb 98dsv such that the size of the escaped string will not exceed "max" chars
9a63e366 99and will not contain any incomplete escape sequences. The number of bytes
4420a417
YO		 100escaped will be returned in the STRLEN *escaped parameter if it is not null.
101When the dsv parameter is null no escaping actually occurs, but the number
102of bytes that would be escaped were it not null will be calculated.
3df15adc 103
ab3bbdeb
YO		 104If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
105will also be escaped.
3df15adc
YO		 106
107Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO		 108but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
109
38a44b82 110If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 111if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 112using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb
YO		 113
114If PERL_PV_ESCAPE_ALL is set then all input chars will be output
681f01c2 115using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
951cbe24 116non-ASCII chars will be escaped using this style; otherwise, only chars above
681f01c2 117255 will be so escaped; other non printable chars will use octal or
72d33970
FC		 118common escaped patterns like C<\n>.
119Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
681f01c2 120then all chars below 255 will be treated as printable and
ab3bbdeb
YO		 121will be output as literals.
122
123If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
72d33970 124string will be escaped, regardless of max. If the output is to be in hex,
c8536afa 125then it will be returned as a plain hex
72d33970 126sequence. Thus the output will either be a single char,
c8536afa 127an octal escape sequence, a special escape like C<\n> or a hex value.
3df15adc 128
44a2ac75 129If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
72d33970 130not a '\\'. This is because regexes very often contain backslashed
44a2ac75
YO		 131sequences, whereas '%' is not a particularly common character in patterns.
