strlen(value: string) -> int64

Returns the number of Unicode code points in the string (character count rather than UTF-8 byte length). A null argument produces a null int64 result.

Domain

This is a scalar function (calculates a single output value for a single input row).

Examples

make_col label_len: strlen(metric_name)

make_col pi_len: strlen("π")

Shows that a single non-ASCII character contributes length one even though it occupies multiple UTF-8 bytes.
