 217
 218 Escapes at most the first "count" chars of pv and puts the results into
 219 dsv such that the size of the escaped string will not exceed "max" chars
 220 and will not contain any incomplete escape sequences.
 221
 222 If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
 223 will also be escaped.
 224
 225 Normally the SV will be cleared before the escaped string is prepared,
 226 but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
 227
 228 If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
 229 if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
 230 using C<is_utf8_string()> to determine if it is Unicode.
 231
 232 If PERL_PV_ESCAPE_ALL is set then all input chars will be output
 233 using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
 234 chars above 127 will be escaped using this style; otherwise, only chars above
 235 255 will be so escaped; other non printable chars will use octal or
 236 common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
 237 then all chars below 255 will be treated as printable and
 238 will be output as literals.
 239
 240 If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
 241 string will be escaped, regardless of max. If the output is to be in hex,
 242 then it will be returned as a plain hex
 243 sequence. Thus the output will either be a single char,
 244 an octal escape sequence, a special escape like C<\n> or a hex value.
 245
 246 If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
 247 not a '\\'. This is because regexes very often contain backslashed
 248 sequences, whereas '%' is not a particularly common character in patterns.
 249
 250 Returns a pointer to the escaped text as held by dsv.
