IIUC Emacs only needs those tables when loading files that use some
particular encodings.  E.g. it doesn't need it to read files using
Unicode encodings.  So couldn't we make sure all the files read during
the dump are using Utf-8 or utf-8-emacs?  Isn't that already the case
for all *.elc files?

What kind of changes?
