Re: [PATCH] locale/ Greek -> ASCII transliteration table [BZ #12031]

Carlos, Rafal,

here is another patch for ASCII transliteration bug [BZ #12031], this time for Greek.

You were instrumental in getting the other patch for the transliteration 

[BZ #2872] approved. So I want to make you aware of this patch. 

Just to make sure, it has nothing to do with Cyrillics. 

It is entirely Greek -> ASCII transliteration table. Yet it has exact same structure 

as [BZ #2872]. So it is only logical if you two could just re-run the same tests you 

did for [BZ #2872].

Given it is Greek there may be other considerations as well of course. Happy to hear 

on this from anyone else any time.

Best regards,
