Symbol contains `а' (CYRILLIC SMALL LETTER A) at character 0, did you mean `a' (LATIN SMALL LETTER A)? The middle line would require Emacs to do a fuzzy search for similar symbols, which may be too much. Something like that could be helpful even in cases where the name has been mistyped (abbrev-changed instead of abbrevs-changed, for example). -- Alan Third
