$Strlencp Aggregation Operator In Mongodb

This article describes the $strLenCP aggregation operator in MongoDB.

Purpose

The $strLenCP aggregation operator counts the number of code points in a string.

Example

Consider the following collection: -

To determine the number of code points for firstname, we will use the following query: -

db.Employees.aggregate([
    {
        $project: {
            firstname: 1,
            nameLength: { $strLenCP: "$firstname" }
        }
    }
])
