+Exceptions:
+- Vim uses "latin1" when 'encoding' is "iso-8859-15".  The euro sign doesn't
+  matter for spelling.
+- When no spell file for 'encoding' is found "ascii" is tried.  This only
+  works for languages where nearly all words are ASCII, such as English.  It
+  helps when 'encoding' is not "latin1", such as iso-8859-2, and English text
+  is being edited.
 
 Spelling for EBCDIC is currently not supported.
 
 A spell file might not be available in the current 'encoding'.  See
 |spell-mkspell| about how to create a spell file.  Converting a spell file
-with "iconv" will NOT work.
-
-If a spell file only uses ASCII characters the encoding can be omitted.  This
-is useful for English: "en.spl"  The file with encoding is checked first, thus
-you could have one with encoding that includes words with non-ASCII characters
-and use the ASCII file as a fall-back.

 			Generate spell file {outname}.spl from Myspell files

+			When the [-ascii] argument is present, words with
