in thread UTF8 URI Escaping

Ok, so anyone have a working example? For example if I add: my $v = decode("UTF-8", $v); In an attempt to decode the aforementioned then I _still_ get: \xc2\xa3

    ... I _still_ get: \xc2\xa3

    How do you tell?  Did you print it to somewhere, etc.?  What exactly do you finally want to achieve?

    In case the idea is to convert the pound sign to Latin-1 encoding, you'd need to encode the decoded string again:

    $v = encode('ISO-8859-1', $v);

    Here's a complete example (note the differences in the PV representations in the 3 dumps):

    #!/usr/bin/perl -w use strict; use Encode; use Devel::Peek; my $v= "%C2%A3"; $v =~ s/%([a-fA-F0-9]{2})/pack('C', hex($1))/eg; Dump $v; my $decoded = decode("UTF-8", $v); Dump $decoded; my $encoded = encode("ISO-8859-1", $decoded); Dump $encoded; __END__ SV = PVMG(0xf98470) at 0xf15d08 REFCNT = 1 FLAGS = (PADMY,SMG,POK,pPOK) IV = 0 NV = 0 PV = 0xf46af0 "\302\243"\0 CUR = 2 LEN = 8 MAGIC = 0xf0f350 MG_VIRTUAL = &PL_vtbl_mglob MG_TYPE = PERL_MAGIC_regex_global(g) MG_LEN = -1 SV = PV(0xeee388) at 0xf16080 REFCNT = 1 FLAGS = (PADMY,POK,pPOK,UTF8) PV = 0xfe40c0 "\302\243"\0 [UTF8 "\x{a3}"] CUR = 2 LEN = 8 SV = PV(0xeee448) at 0xf16110 REFCNT = 1 FLAGS = (PADMY,POK,pPOK) PV = 0xfd44c0 "\243"\0 CUR = 1 LEN = 8
