This is the {{tl|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: 

:<code><nowiki>{{str len}}</nowiki></code> returns {{str len}}
:<code><nowiki>{{str len|}}</nowiki></code> returns {{str len|}}
:<code><nowiki>{{str len| }}</nowiki></code> returns {{str len| }}

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

:<code><nowiki>{{str len| ab cde }}</nowiki></code> returns {{str len| ab cde }}
:<code><nowiki>{{str len| 1234567 }}</nowiki></code> returns {{str len| 1234567 }}
:<code><nowiki>{{str len| café åäö }}</nowiki></code> returns {{str len| café åäö }}
:<code><nowiki>{{str len| </nowiki>{{tlp|loop|50|abcdefghij}}<nowiki> }}</nowiki></code> returns  {{str len| {{loop|50|abcdefghij}} }}
:<code><nowiki>{{str len| </nowiki>{{tlp|loop|10000|abcdefghij}}<nowiki> }}</nowiki></code> returns  {{str len| {{loop|10000|abcdefghij}} }}
