Bilin / Chaha Extended GHA Series Labioveler Extensions
The logical series of 5 extensions for the Bilin and Chaha GHA consonant series were found in one German references (not available). They are also provided in the ModEth software font tables. It is not known precisely by what languages the extensions are used though are believed to be Agew [15] :

Admas Concepts Generic Labioveler Extensions
The following series of 5 labiovelar extensions were introduced in 1994 by one software house as a means to provide extended lalibalized forms phonetically when a unique letter was not available. PWEE for example would be rendered with P + WWEE (the first of the series below). The characters may be found in Multilingual Emacs.

These extensions are not in use by the writing systems of any language. They should then be considered private use characters.
Infrequent Dikala-Rab' Orders
The Dikala-Rab' orders of SZAE, YAE, and PAE are sometimes encountered in Ethiopic manuscripts. These forms may be given code assignment without compromising the current matrix and without the requirement that the characters reside in the extension zone. Logical address are given [4, 5, 8, 9, 10] :
| U+1227 | U+12EF | U+1357 |

Leslau Extensions For Chaha
Character coding of the Chaha labiovelar extensions is left for a later revision of the Unicode standard. It will be important for the inclusion of the extensions that additional manuscripts, and preferably documents from the present day, be found to support their use in writing practices.

Proposed coding of the Chaha and and Bilin labialized extensions is offered in Appendix A with a compactified vertical (trans-row) ordering. The scheme's principle is revealed most readily by visual inspection of the matrix. This coding scheme for labialized extensions makes for the efficient use of available space and allows additional labialized extensions to be added cleanly when the need arises.
Extensions For Sidamigna
The following were devised for Sidamigna during a literacy campaign of the early '80's. Shown below is the first of a series of 7 for each syllable class. These characters were found at the Academy of Ethiopian Languages, their acceptence and use in print by the Sidamigna language speakers is unkown.
