That mapping (and internal.el in general) is used by the MS-DOS build of Emacs to allow a legible display of characters that the DOS codepage doesn't support. > I can't find more mappings in the source code, ucs-normalize.el say= s > that Punctuation is excluded from Normalization: >=20 > ;; HFS Normalization excludes following area for decomposition. > ;; U+02000 ..

This is not a normalization issue. This is about an Emacs specific feature, and should be treated as such. We should begin by discussing whether we really want this feature, by default or otherwise. One of the aspects we need to consider, IMO, i= s what do spell-checkers do with these characters: if they don't treat them as word-constituents, that would be one argument against the change; if they do, it's an argument for the change. > Maybe the Unicode standard has a separate document for equivalence = mappings > for punctuation. I can found only the following table. Is this wh= at is needed? >=20 > http://unicode.org/cldr/charts/supplemental/character_fallback_subs= titutions.html This seems to be relevant to display, not to the issue at hand. If anything, it should tell us to treat ' as we treat =E2=80=99, not the= other way around.
