This is increasingly untrue. This is not to say that the increase in willingness to allow Books of Shadows and other such works to be read, whether by other practitioners or by academics, necessitates the exchange of Theban characters.
It still remains the case that Theban "orthography" is basically English, that is, it is Latin with funny glyphs.
