escaping the | symbol

thinkr

Hello, I tried using URL Redirect to redirect a bogus URL that contained a | symbol. I tried escaping the character with a backslash: \. However, the resulting \| still treats the | like an OR, not a character. How do I succeed in escaping the pipe symbol? Or is this a problem with my very old version of abyss x2 v2.8?

This isn't too hard to achieve. I'm using X2 v2.8 as well.
Here's the code I used.
Virtual path regex:

^/[^\|]*\|[^\|]*$

It catches any URL with the pipe in it (including JUST the pipe).

If anyone is still looking for how to do this, you can read this:

\0dd character with octal code 0dd
\ddd character with octal code ddd, or back reference
\o{ddd..} character with octal code ddd..
\xhh character with hex code hh
\x{hhh..} character with hex code hhh.. (non-JavaScript mode)
\uhhhh character with hex code hhhh (JavaScript mode only)

(4) \u matches a lower case "u" character unless it is followed by four
hexadecimal digits, in which case the hexadecimal number defines the
code point to match. By default, \u causes a compile time error (Perl
uses it to upper case the following character).

That means you can do this to escape the | character:

\x{7C}

\u007C

0x7C is the hex byte that represents the | character.
0x5C is the one for \ (if you need it).
You can use any hex editor to find the hex value for a character.

Constraints on character values
Invalid Unicode codepoints are the range 0xd800 to 0xdfff (the so-
called "surrogate" codepoints), and 0xffef.
