The accent is inserted as signle character until there is a valid
character for it to "combine" e.g ΄΄΄ά.  If a valid character, such as
vowel, is inserted after the accent, they combine into one character
(ά), if the user inserts a character that takes no accents, such as
pi(π), the accent is inserted as a signle character as well (e.g ΄π).

There are no characters in Greek with multiple accents of the same type.
