error duing `copilot--on-doc-change` in vertico completions

[offbyone]

I've just started, after a recent doom update, getting an error the first time I try select a completion from the minibuffer using vertico. The traceback implicates copilot-mode's copilot--on-doc-change function. I am not sure why this is happening or how to get you better debugging info, but something is fishy here:

It is caused by:

1. copilot-mode is enabled in your mini buffer.
2. There is a non-utf8 character in your mini buffer.

To solve the problem, you may want to disable global-copilot-mode and enable copilot-mode only on necessary modes or buffers.
