George, Polytonic Greek is a complicated issue, mainly because of the distinction between combining diacritical marks (which most software today doesn't support well) and precomposed combinations of letters and marks. If you looked on the Unicode website under the Greek range you didn't find dasia, vrachy, etc., because those are in the combining marks area, and in most cases are unified with Latin punctuation marks (grave, acute, etc.). A complete Greek polytonic font will include characters from several ranges of Unicode.
See my web site http://members.telocity.com/~perryd/ and download a copy of my booklet; read the introduction (which describes basic Unicode principles) and the chapter on Greek. At the end of that chapter is a complete set of code charts for the Greek and Greek Extended ranges of Unicode. This is not written as a font designer's handbook, but I think that you will find the information you need there if you cannot find it more conveniently elsewhere. Best wishes, David #Thank you very much for your help, #but i still cant find the unicode standart for symbols #such as "oxia" "perispomeni" "dasia" "upogegrameni" #etc... in order to write polytonic text under windows #2000 or xp. #thank you again. # #George lyngkas #student of graphic Arts # #--- "Magda Danish (Unicode)" <[EMAIL PROTECTED]> #wrote: #> George, #> #> Have you looked at the code charts on our website at #> http://www.unicode.org/charts/PDF/U0370.pdf #> #> I hope this is helpful. #> #> Best Regards, #> #> Magda Danish #> Administrative Director #> The Unicode Consortium #> 650-693-3921
