Double-Struck Numerals in Nemeth Output Lack the Numeric Indicator

Issue

It seems that double-struck numerals are rendered without the numeric indicator in Nemeth. For instance, $\mathbb 1$ (double-struck 1), often used to denote the identity matrix, is rendered as ⠈⠂ (dot 4, dot 2) instead of ⠈⠼⠂ (dot 4, dots 3-4-5-6, dot 2).

It also seems that double-struck numerals are not distinguished from other numerals in "Terse" verbosity for any speech style.
