+Source file encoding
+--------------------
+
+Most Emacs source files are encoded in UTF-8 (or in ASCII, which is a
+subset), but there are a few exceptions, listed below.  Perhaps
+someday these files will be converted to UTF-8, for convenience when
+using tools like 'grep -r', but this might need nontrivial changes to
+the build process.
