Based on our analysis, we've identified that the file “EncodingMap.java” includes an entry where "ISO-8859-8-I" is defined as an alias for "ISO8859_8." This entry is found in the headstream repository, and we believe it makes sense to include this in the charsets file as well. You can reference the relevant section here: [EncodingMap.java](https://github.com/openjdk/jdk/blob/5381f553ad61ddaa44d49c3039a05511cc68bdd0/src/java.xml/share/classes/com/sun/org/apache/xerces/internal/util/EncodingMap.java#L770).

Moreover, the original bug submitter has expressed agreement with our proposed solution, as noted in the discussion [here](https://github.com/openjdk/jdk/pull/20690#issuecomment-2354559575).

If we decide to create a new charset mapping for "ISO-8859-8-I," it would essentially mirror "ISO-8859-8," differing only in the naming convention. This would function similarly to creating an alias in the charsets file.

Therefore, we propose that this approach is valid and appropriate for implementation.
