It's indeed a bug that
(eq utf-8-translation-table-for-decode
(get 'utf-8-translation-table-for-decode 'translation-table))
=> nil
I noticed this code in international/characters.el:
(modify-category-entry (make-char 'greek-iso8859-7) ?g)
(let ((c #x370))
(while (<= c #x3ff)
(modify-category-entry (decode-char 'ucs c) ?g)
(setq c (1+ c))))
My understanding is that the first line is sufficient to put all
characters from the charset `greek-iso8859-7' into the category ?g.
Then the purpose of the remaining lines must be to add Greek Unicode
characters into the category ?g, but they do not do that; instead,
they add the corresponding characters from greek-iso8859-7 in again.
So it looks like this bug has at least one practical consequence:
Greek Unicode characters are not put into the category ?g.
It occurred to me that even after this bug is fixed, the problem
would remain if utf-8-fragment-on-decoding were enabled while this
code is executed. However, this code is executed before the user
has a chance to enable the option, right? So as long as fragmentation
is not the default, that will be ok.
