Dear Maintainer,
When attempting to rip a CD, when clicking "Go" it crashes with:
```
(ripperx:992520): Pango-WARNING **: 15:07:52.849: Invalid UTF-8 string passed to pango_layout_set_text()
Segmentation fault (core dumped) ripperx
```
This seems similar to #512898 though I don't think it's the same, since
that's 7 years old and basedon a different version.
The CD in question has one track where the UTF doesn't parse properly:
```
(Whata��s So Funny a��bout) Peace, Love and Understanding
```
CD is "Other Worlds" by The Pretty Reckless.
Here's a full backtrace:
```
