DahDahDahDit has no character listed on the tree. It decodes as “Ó” (with the diacritical) in some translators.

Two other symbols (DahDahDahDah and DitDitDahDah) also have no character mapped. In some translators, they decode to “Ĥ” and “Ü”, respectively, but those characters are not used in English and are not listed on this tree.

Those positions are included in the tree only because they are steps to get to Zero (DahDahDahDahDah) and Two (DitDitDahDahDah)

The tree has no punctuation listed.
