--- Comment #5 from Alexander Ploumistos alex.ploumistos@gmail.com --- Well, I reported the issue to the maintainer listed here: http://mirrors.ctan.org/fonts/tex-gyre/doc/fonts/tex-gyre/README-TeX-Gyre-He...
Today I noticed that the same file reads: "If you know about European languages that are not covered completely or if some glyphs have apparently wrong shapes -- please let us know. Note, however, that Greek glyphs bear provisional character." I guess that means it won't get fixed anytime soon.
