Description

On Ubuntu 24.04, run: $ cargo run --example match-font -- "Ubuntu"

Output:

Path: /usr/share/fonts/truetype/ubuntu/Ubuntu[wdth,wght].ttf
Index: 393216
Family name: Ubuntu
PostScript name: Ubuntu-ExtraBold
Style: Normal
Weight: Weight(400.0)
Stretch: Stretch(1.0)

Interesting $ fc-match "Ubuntu :weight=400" has the same error, but Firefox matches the correct font.
