ab3bbdeb 221dsv such that the size of the escaped string will not exceed "max" chars
3df15adc

ab3bbdeb
YO		 224If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string

3df15adc
YO		 226
227Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO		 228but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
229
38a44b82 230If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 231if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 232using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb
YO		 233
234If PERL_PV_ESCAPE_ALL is set then all input chars will be output
681f01c2
KW		 235using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
236chars above 127 will be escaped using this style; otherwise, only chars above
237255 will be so escaped; other non printable chars will use octal or
238common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
239then all chars below 255 will be treated as printable and
ab3bbdeb
YO		 240will be output as literals.
241
242If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
c8536afa
KW		 243string will be escaped, regardless of max. If the output is to be in hex,
244then it will be returned as a plain hex
245sequence. Thus the output will either be a single char,
246an octal escape sequence, a special escape like C<\n> or a hex value.
3df15adc 247
44a2ac75
YO		 248If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
249not a '\\'. This is because regexes very often contain backslashed
