number of characters in a string

[machoq]

I have reading a line from a text file
the line is like

abc\"123
I need to find the number of characters in this string... (which
should be 8, however if i do a

$var = $line;
print length($var); i get 7

How do i workaround it ?
regards
-Machoq !

Well if the line is "abc\"123", then the \ would be counted as a
backreference for the " character. Therefore, \" is only counted as
one character. This is only a guess though since you didn't post the
exact code.

If the line is being read from a text file, as the OP claimed, than this
is not true. The \ will be a literal \. \ is only treated 'special'
within literal code, not within data.

^^^^^^^^^^^^^

Backreferences are a different case of "\". You mean "quote" or "escape"
(sometimes called "backwhack").
