I prefer passing it via a parameter so that, should the imagination kick in, we
can get more inventive regarding what gets translated when.

As long as the array identifies non-first characters of sequences, BRLTTY could
easily enforce that only the first character of a sequence can be used when
cutting. Better yet, the first character should be used for the start of the
selected text, but the last character should be used for the end of the
selected text. The array, however, need only mark the first character of each
sequence, as BRLTTY could easily figure out the rest.
