[EP-tech] subject tree sorting is not 100% correct

[pgasinos pgs]

I noticed that subjects sorting are not 100% correct in Greek Language (and
perhaps in other languages too). Subjects.xml is in utf-8 and the
everything seems to be in the correct order but I have noticed that the
subjects that have an accent in Greek in the first or second letter come
first in the list and after those everything is in the correct order. In
Greek language a vowel with accent is the same character with the vowel
without accent. It is just a matter of correct spelling. Is there any
solution to that problem?
