Takes one parameter, a Source value

Description:

Returns the number of bytes in the given Source value, as a string.

This is a similar command to Len%, which returns the byte count as an integer.

Note: Moxie.Build is configured for all pages / data to be in UTF-8. The Len$, Right$, and Left$ functions reference byte counts, not character counts. All non-accented Latin characters, as is normal in English, are one byte per character. However, accented characters and non-Latin characters will be multiple bytes per character. Consideration of these limits should always be used when designing code that uses Len$, Right$, and Left$.
