A number <strong>555555555</strong> then some more text and a quoted number "(123)4567890" and then <strong>1 2 3 4 6 (54) 3 -2</strong> and forward slashed /+--------0/ versus <strong>+--------0</strong> then something more realistic '234 588 9191' no more text. This is not closed by the same character on both ends: "<strong>+012345678901</strong>/ which of course is a _necessary_ check?
