I suspect with this change, textIsUTF8 will *always* be `true`. Are you actually seeing messages with subjects that are *not* valid UTF-8?

All ASCII strings are valid UTF-8, while not all UTF-8 strings are valid ASCII.

You probably mean to write something more like this:
```
str_is_ascii(str) === false && str_is_utf8(str) === true
```

Logically that makes sense, though it has the same effect in the message list either way. I've updated it to check this way and pushed my changes, and ran another build pipeline.
