Template:Str len/doc

This is the str len meta-template.

It takes a string as parameter and returns its length (excluding spaces at the start and end). It can now count as high as necessary.

Examples
If the parameter is empty or undefined it is considered to be of zero length:


 * returns 0
 * returns 0
 * returns 0

It counts the length correctly, even if the string contains spaces, looks like a number, or contains special characters:


 * returns 6


 * returns 7


 * returns 8


 * returns 499
 * returns 1000
