Best way to count the characters of a string

[Boba Fonts]

Which is the best way to count the number of characters in any kind of string?

Using Len("Hello World") in the expression editor should do the trick.

Len() has been in the expression editor right in front of me for years and I had never used it before!
Thank you danworth
