in the Emacs tree "grep -r" is probably just a bug.
Although "grep -r" doesn't conformto POSIX, it is a handy GNU extension, and I use it a lot, both in the Emacs source tree and elsewhere. GNU grep works reasonably well even with text files in the "wrong" encoding, and even with non-text files. I don't expect grep to match UTF-8 patterns to the corresponding EUC-JP text, because I know it doesn't translate.
Emacs's M-x grep command supports this usage well, and I don't see how it would be an improvement to call this usage a "bug" or for the Emacs (or grep) default to insist on strict coding correctness here.
Eli is correct that UTF-8 is the encoding typically used for text in the Emacs source code. For more about this, please see "Source file encoding" in admin/notes/unicode.
