What
About eighty more look-alike code points (Latin small capitals, Cherokee, Yi radicals, Armenian, Coptic, Cyrillic) now map to their ASCII letters. A bug where the table's uppercase-derivation step could rewrite genuine ASCII characters is fixed by refusing any mapping whose uppercase form is itself a plain ASCII letter.
Details
The guard is !/^[A-Za-z]$/.test(n) in the loop that extends the table.
Evidence
!/^[A-Za-z]$/.test(n)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
