Greetings, To compose coptic numerals under Unicode I've applied the appropriate lowercase letters in the Greek-Coptic range with the elements from the Combining Diacritical Marks: U+0304, U+0331 and U+0347. I had no basis to choose these diacritical symbols upon other than they seemed to get the job done visually. What are the "approved" symbols for composing coptic numbers portably?
Next question; what does one do for character codes to show values over a billion? If there is no official sanctioned solution, it occured to me that the diacritic symbols could simply accumulate following the lowercase char for interchange and then be presented graphically. Some recommendation added to the "The Unicode Standard" reference would be a good service here, sorry if I've missed it. thanx, /Daniel
