ACS5 Puerto Rico names (seems like more than usual have spec char?)

I know that there are names that contain special characters, but it seems as if Puerto Rico has more than I remember and I cross-checked against an old list I had and these dont match. I had fun with Connecticut names and changes in the past.  I looked here ( https://www.census.gov/programs-surveys/acs/technical-documentation/table-and-geography-changes/2023/geography-changes.html) but did not find the changes. Is there a better place that covers name changes and related. I also looked here ( https://www.census.gov/programs-surveys/geography/technical-documentation/boundary-change-notes.2023.html#list-tab-1518919262 ).

Any help is appreciated.
