Ethiopic Gematria

The Ethiopic alphabet is a 'syllabary'—each letter represents a consonant + vowel (using the Unicode transliteration).

One form of Ethiopic gematria was to equate the Ethiopic characters with the phonetically equivalent Hebrew letters and their gematria values. This does have the advantage that (theoretically, at least) proper names will preserve their gematria values when transliterated between the two languages.
