Except there are standalone Greek/Coptic as well as Cyrillic ranges in Unicode. Latin A, Greek A, and Russian A each has its own versions in Unicode, so that Latin or Russian fonts don't have to be deleted from apps and operating systems configured for Greek usage to show Greek :alpha: consistent with Greek :phi: without getting it substituted by lowercase Latin `a`.
