# SW31007: Invalid UTF-16 position

This error occurs when an integration or a tool asks for a line and column that
do not exist in the source. Lines count from zero, and columns count UTF-16 code
units from zero.

## How to fix

- With an official integration, report the error with the file and the action
  that caused it.
- In your own integration, convert positions from one-based editor numbers, and
  compute them again after each edit. Do not use positions in the converted
  script as positions in the original component.
