First, I think the paper is a fantastic summary.

Second, the encoding list in the Google Sheet may contain some false
positives. As a Chinese, I noticed the weird GBGBK immediately. I have no
idea what it is, and googling does not reveal interesting results, and
GBGBK does not exist on macOS (Sequoia) or Ubuntu (24.04 LTS). Claude
Sonnet says it might be an internal conversion module, but it does not give
much detail. Currently I do not think it is worthwhile to dig out what it
really is.

I think there are fewer in-use encodings that require digraphs than the
spreadsheet implies. From what I can recognize, GBBIG5 may be similar to
GBGBK. What is ISO646 (as versus ISO646-something), which does not really
make sense? On macOS there is an ISO646-BASIC:1983 (I don't see
an equivalent on Ubuntu), but it behaves differently than the spreadsheet
too.

My 2 cents.
