I'm not an expert, but obviously computers make a difference between the
two versions of the characters.
We are talking about this series:
U+1F70 - U+1F7D:    ὰ     ά     ὲ     έ     ὴ     ή     ὶ     ί ὸ     ό
    ὺ     ύ     ὼ     ώ
Is it possible to filter / limit in some way the redirection in the
script to this range?
