[tex4ht] [bug #236] using {newtxtext, newtxmath} packages breaks MathML generation in tex4ht

[Wojciech Myszka]

Orogate (also orogate) is taken from polish rogate o (which means letter o
with horns).

Still do not known if the letter has unicode equivalent, but probably can
(or can not) be found in TeX-Gyre fonts:
