You have non-ascii characters in your code

If you're having trouble finding where then you can use pattern matching to find characters outside that range:

/[^[:ascii:]]/
or
/[^\x00-\x7F]/

There are lots of tools that can use those expressions, here's an online one that you can use: https://regex101.com/
