ab3bbdeb 220dsv such that the size of the escaped string will not exceed "max" chars
3df15adc

ab3bbdeb
YO		 223If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string

3df15adc
YO		 225
226Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO		 227but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
228
38a44b82 229If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 230if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 231using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb
YO		 232
233If PERL_PV_ESCAPE_ALL is set then all input chars will be output
681f01c2
KW		 234using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
235chars above 127 will be escaped using this style; otherwise, only chars above
236255 will be so escaped; other non printable chars will use octal or
237common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
238then all chars below 255 will be treated as printable and
ab3bbdeb
YO		 239will be output as literals.
240
241If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
c8536afa
KW		 242string will be escaped, regardless of max. If the output is to be in hex,
243then it will be returned as a plain hex
244sequence. Thus the output will either be a single char,
245an octal escape sequence, a special escape like C<\n> or a hex value.
3df15adc 246
44a2ac75
YO		 247If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
248not a '\\'. This is because regexes very often contain backslashed
