You are misguided by obsolete comments in src/LYCharSets.c.
Current character translation mechanism based on tables
from src/chrtrans/*.tbl which allows multichars replacements,
and 7-bit approximation are from def7_uni.tbl table
(with "U+20AC:EUR" entry for EURO, literrally
"EUR" replacement string for Unicode 0x20AC symbol)

I beleave LYCharSets.c tables should be removed one day
but they are still used for certain internal needs...
(as I understand it connects closely to HTPassEightBit* flags
so chars from 160-255 region _may_ be conversed to ISO Latin1 &name; entities
and than translated back to 8bit char on a later stage).
