With the latest patch it's optional, enabled by 'completions-detailed', but an additional option could be added - specific to grouping only in read-char-by-name. > Btw, just switching the order doesn't yet guarantee the names will > align, because characters are not guaranteed to have the same width on > display.

I tried TAB with tab-width=3, but some characters are still wider than 3. Then I tried 'char-width' on these characters, but 'char-width' returns 1 for wide characters. This is strange, I expected it to return 4 for characters wider than tab-width=3.
