 216
 217 Escapes at most the first "count" chars of pv and puts the results into
 218 dsv such that the size of the escaped string will not exceed "max" chars
 219 and will not contain any incomplete escape sequences.
 220
 221 If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
 222 will also be escaped.
 223
 224 Normally the SV will be cleared before the escaped string is prepared,
 225 but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
 226
 227 If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
 228 if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
 229 using C<is_utf8_string()> to determine if it is Unicode.
 230
 231 If PERL_PV_ESCAPE_ALL is set then all input chars will be output
 232 using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
 233 non-ASCII chars will be escaped using this style; otherwise, only chars above
 234 255 will be so escaped; other non printable chars will use octal or
 235 common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
 236 then all chars below 255 will be treated as printable and
 237 will be output as literals.
 238
 239 If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
 240 string will be escaped, regardless of max. If the output is to be in hex,
 241 then it will be returned as a plain hex
 242 sequence. Thus the output will either be a single char,
 243 an octal escape sequence, a special escape like C<\n> or a hex value.
 244
 245 If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
 246 not a '\\'. This is because regexes very often contain backslashed
 247 sequences, whereas '%' is not a particularly common character in patterns.
 248
 249 Returns a pointer to the escaped text as held by dsv.
