Some observations:
1: This PR seems to have been abondoned, so perhaps this discussion belongs in
#15694 ?
2: The `å` (Unicode 'Latin small letter a with ring above' U+00E5) was
correctly encoded as 0xEF in ISO-8859-1 previous to this change.
3: The conversion changed this `0xEF` to the three-byte sequence `ef bf bd`
4: This is as-if the file was incorrctly decoded using UTF-8, then encoded
using UTF-8:
byte[] origBytes = "å".getBytes(StandardCharsets.ISO_8859_1);
String decoded = new String(origBytes, StandardCharsets.UTF_8);
byte[] encoded = decoded.getBytes(StandardCharsets.UTF_8);
String hex = HexFormat.of().formatHex(encoded);
assertEquals("efbfbd", hex);
```
Like @magicus I'm worried that similar incorrect decoding could have been
introduced by the same script in other files.
