#/mainspace nonredirects by shortdesc length

This query is marked as a draft This query has been published by Cryptic.

Number of mainspace, non-redirect pages with each short description length, combining 100+.

The length field is mislabelled; the number is the length in bytes, not characters.  This makes a difference for characters not represented in one byte in UTF-8 (é, for example, is one character but two bytes).

For [[WP:RAQ#Request for table showing the length of short descriptions in article space]] circa 24 June 2022.
