218Escapes at most the first "count" chars of pv and puts the results into
ab3bbdeb 219dsv such that the size of the escaped string will not exceed "max" chars
3df15adc
YO		 220and will not contain any incomplete escape sequences.
221
ab3bbdeb
YO		 222If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
223will also be escaped.
3df15adc
YO		 224
225Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO		 226but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
227
38a44b82 228If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 229if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 230using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb
YO		 231
232If PERL_PV_ESCAPE_ALL is set then all input chars will be output
681f01c2
KW		 233using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
234chars above 127 will be escaped using this style; otherwise, only chars above
235255 will be so escaped; other non printable chars will use octal or
236common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
237then all chars below 255 will be treated as printable and
ab3bbdeb
YO		 238will be output as literals.
239
240If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
c8536afa
KW		 241string will be escaped, regardless of max. If the output is to be in hex,
242then it will be returned as a plain hex
243sequence. Thus the output will either be a single char,
244an octal escape sequence, a special escape like C<\n> or a hex value.
3df15adc 245
44a2ac75
YO		 246If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
247not a '\\'. This is because regexes very often contain backslashed
248sequences, whereas '%' is not a particularly common character in patterns.
