ab3bbdeb 218dsv such that the size of the escaped string will not exceed "max" chars
3df15adc

219and will not contain any incomplete escape sequences.
220
ab3bbdeb
YO
221If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
222will also be escaped.
3df15adc
YO
223
224Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO
225but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
226
38a44b82 227If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 228if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 229using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb
YO
230
231If PERL_PV_ESCAPE_ALL is set then all input chars will be output
681f01c2
KW
232using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
233chars above 127 will be escaped using this style; otherwise, only chars above
234255 will be so escaped; other non printable chars will use octal or
235common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
236then all chars below 255 will be treated as printable and
ab3bbdeb
YO
237will be output as literals.
238
239If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
c8536afa
KW
240string will be escaped, regardless of max. If the output is to be in hex,
241then it will be returned as a plain hex
242sequence. Thus the output will either be a single char,
243an octal escape sequence, a special escape like C<\n> or a hex value.
3df15adc 244
44a2ac75
YO
245If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
246not a '\\'. This is because regexes very often contain backslashed
247sequences, whereas '%' is not a particularly common character in patterns.
