Converts text to/from six-dot Braille using common English Braille rules. Conversion to Braille is simple, using only single letter blocks. Conversion from Braille will decode multiletter fragments (eg dots 346 "⠬" for "ing" or dots 2346 "⠮" for "the"). Those multiletter groups are only valid in certain contexts, which this converter is not smart enough to understand. The multiletter group for "and" (dots 12346) is used for the ampersand symbol.
Note that various punctuation characters have more than one meaning — dots 2356 "⠶" can mean double-quote (") or either square bracket ("[" and "]") — but this decoder just picks one meaning all the time.
If all you see are empty boxes, the fileformat.info list of fonts that support Braille may help.
The output is fully cut-n-pastable text.
