charLength(string $expression) : string

This helper wraps the ArangoDB AQL function CHAR_LENGTH(str) which returns the number of characters in a string, counting Unicode characters properly rather than bytes.

Example AQL usage:

CHAR_LENGTH("hello")          // returns 5
CHAR_LENGTH("café")           // returns 4 (not 5 bytes)
CHAR_LENGTH(doc.title)        // returns character count of title
Parameters
$expression : string

String expression to count characters of.

// Produces: 'CHAR_LENGTH(doc.title)'
