Normally the SV will be cleared before the escaped string is prepared,
but when C<PERL_PV_ESCAPE_NOCLEAR> is set this will not occur.
-If C<PERL_PV_ESCAPE_UNI> is set then the input string is treated as UTF-8
-
if C<PERL_PV_ESCAPE_UNI_DETECT> is set then the input string is scanned
+If C<PERL_PV_ESCAPE_UNI> is set then the input string is treated as UTF-8.
+
If C<PERL_PV_ESCAPE_UNI_DETECT> is set then the input string is scanned
using C<is_utf8_string()> to determine if it is UTF-8.
If C<PERL_PV_ESCAPE_ALL> is set then all input chars will be output
-using C<\x01F1> style escapes, otherwise if C<PERL_PV_ESCAPE_NONASCII> is set, only
-non-ASCII chars will be escaped using this style; otherwise, only chars above
-255 will be so escaped; other non printable chars will use octal or
-common escaped patterns like C<\n>.
-Otherwise, if C<PERL_PV_ESCAPE_NOBACKSLASH>

-If C<PERL_PV_ESCAPE_RE> is set then the escape char used will be a C<"%"> and
