For ISO 8859-3, the answer is in the wiki: http://en.wikipedia.org/wiki/ISO/IEC_8859-3
"It was designed to cover Turkish, Maltese and Esperanto, ..." The answer for IBM CP905 is simple -- it is simply the EBCDIC code page of June, 1986 that corresponded to ISO 8859-3. That also covers the answer for ISO-IR 109, which is simply the registration of the right-hand part of Latin-3. At any rate, since I didn't check first whether the Esperanto letters were in ISO 8859-3 before I wrote my initial response, this would certainly remove all proximate speculation about the occurrence of the accented letters for Esperanto in the Unicode 1.0 repertoire in Latin Extended-A. They were included by the exercise of doing the union of all the 8859 Latin alphabets. So the answer for Unicode is, instead, *yes*, they were in a pre-existing standard that was grandfathered in to the initial collection of accented Latin letters. And the question, instead, then becomes tracking down through the ancient history of JTC1/SC2/WG3 (<-- Note *3*, not *2*), why the participants who drafted 8859-3 felt it was important to include the Esperanto letters in the repertoire for the South European set back in 1986. That date, by the way, is earlier than anything I have firsthand records for. --Ken On 3/23/2015 10:10 AM, Leo Broukhis wrote:
