SW31008: Invalid UTF-8 offset

A requested byte offset is outside the source or inside a multibyte character.

View as Markdown

This error occurs when an integration or a tool asks for a UTF-8 byte offset that is outside the source, or that falls inside a character of several bytes.

How to fix

With an official integration, report the error with the file and the action that caused it.
In your own integration, use byte offsets for byte-based APIs. Convert UTF-16 editor positions with the source service instead of counting characters.
