Theme

Expected behavior

When I'm running shopify theme dev, files that I change should be synced to the remote dev theme without errors related to character encodings.

Actual behavior

When I make changes to a file and save, Shopify CLI tries to sync them but frequently errors out because of "incompatible character encodings: UTF-8 and ASCII-8BIT". If I cut and paste recent changes the error usually goes away, so it doesn't seem like there's actually anything wrong with the new code that was written. This only started happening in the last week or. I'm not sure if it's Shopify CLI or something else, but if someone could help me troubleshoot I'd really appreciate it.
