you can count the number of characters in a string by using the length() function:

$number = length($string);

but that counts everything.

If you only wanted to count letters, as in the alphabet (a-z) this will work:

$count++ while $string =~ /[a-zA-Z]/g;

I believe this also works and might be faster:

$count = ($string =~ tr/a-zA-Z//);
