G'day ic23oluk,

I see you've been given lots of advice on how to handle that specific character.

From your question, it appears that you may be attempting to hard-code each character and ASCII value. That's a lot of effort, and quite unnecessary, for your stated task: "ascii signs as keys, and the corresponding numbers as values". You can do that with a single statement: 

my %hash = map { chr $_ => $_ } 32 .. 126;

That will give you a table of all, printable, 7-bit ASCII characters and their corresponding decimal values. You can test it like this: 

$ perl -e 'use Data::Dump; my %h = map { chr $_ => $_ } 32 .. 126; dd 
+\%h'
{
  " "  => 32,
  "!"  => 33,
  "\"" => 34,
...
  "|"  => 124,
  "}"  => 125,
  "~"  => 126,
}

Take a look at sprintf, if you want to format the values as hexadecimal, Unicode code points, HTML entity references, or something else. For example, 

$ perl -e 'use Data::Dump; my %h = map { chr $_ => sprintf "U+%04X", $
+_ } 32 .. 126; dd \%h'
{
  " "  => "U+0020",
  "!"  => "U+0021",
  "\"" => "U+0022",
...
  "|"  => "U+007C",
  "}"  => "U+007D",
  "~"  => "U+007E",
}

[Aside: I'm guessing English isn't your first language. The word you were looking for in your OP is "assign" ('n' and 'g' order reversed). The word "assing" means something else: I'll leave you to follow that link if want a chuckle. :-)]
