Bug 2008011 [wpt PR 56945] - script: More thoroughly convert between UTF-16 and UTF-8 offsets in text inputs, a=testonly
Automatic update from web-platform-tests
script: More thoroughly convert between UTF-16 and UTF-8 offsets in text inputs
DOM APIs for interacting with selection and text in text inputs
`<input type=text>` and `<textarea>` all accept offsets and lenghths in
UTF-16 code units. Servo was not converting all of these offsets into
UTF-8 code units. This change makes it so that this conversion is done
more thoroughly and makes it clear when the code is dealing with UTF-8
offsets and UTF-16 offsets.
Helper functions are added for doing this conversion in both directions
as it is necessary. In addition, a `char` iterator is added for
`TextInput` as it is useful for doing this conversion. It will be used
more completely in the future when a `Rope` data structure is extracted
from `TextInput`.
Finally, specification text is added to all of the DOM implementation
touched here.
