167Escapes at most the first "count" chars of pv and puts the results into
ab3bbdeb 168dsv such that the size of the escaped string will not exceed "max" chars
3df15adc
YO
169and will not contain any incomplete escape sequences.
170
ab3bbdeb
YO
171If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
172will also be escaped.
3df15adc
YO
173
174Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO
175but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
176
177If PERL_PV_ESCAPE_UNI is set then the input string is treated as unicode,
178if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
179using C<is_utf8_string()> to determine if it is unicode.
180
181If PERL_PV_ESCAPE_ALL is set then all input chars will be output
182using C<\x01F1> style escapes, otherwise only chars above 255 will be
183escaped using this style, other non printable chars will use octal or
184common escaped patterns like C<\n>. If PERL_PV_ESCAPE_NOBACKSLASH
185then all chars below 255 will be treated as printable and
186will be output as literals.
187
188If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
189string will be escaped, regardles of max. If the string is utf8 and
190the chars value is >255 then it will be returned as a plain hex
191sequence. Thus the output will either be a single char,
192an octal escape sequence, a special escape like C<\n> or a 3 or
193more digit hex value.
