in thread special characters in parsed json rendering badly in browser

\x refers to hex encoding, so \x{2018} is a two-byte encoding of chr(32) and chr(30) (32 decimal = 20 hex). So it's one of the 16 bit character encodings, though from this alone I am unsure which. See replies for more info.

    so \x{2018} is a two-byte encoding of chr(32) and chr(30)

    Sorry, but no, this is incorrect. \x{2018} is not valid JavaScript, so I'm assuming it's Perl. In Perl, \x{2018} is interpreted as the Unicode character U+2018, LEFT SINGLE QUOTATION MARK, decimal 8216. Although one normally shouldn't have to worry about the internal encoding Perl uses, here it is anyway:

    $ perl -CSD -MDevel::Peek -le 'my $x="\x{2018}"; Dump($x); print "<$x>"'
    SV = PV(0x2147e80) at 0x21675b0
      REFCNT = 1
      FLAGS = (POK,IsCOW,pPOK,UTF8)
      PV = 0x21694e0 "\342\200\230"\0 [UTF8 "\x{2018}"]
      CUR = 3
      LEN = 10
      COW_REFCNT = 1
    <‘>
    

    Minor fixes.
