Language of the Hunter x Hunter World

I suppose this isn't very clear if you don't know
Hiragana, but here's the Hiragana in Romaji(english letters): Some interesting
things:

is "ma" in romaji, and the symbol in Hunter
language is a sideways capital "M"
Likewise,

is "ha", and the symbol is a
sideways "H".
--

is "na" and its symbol is a sideways "N"
--

is "ta" and its symbol is an upside down
"T"
--

is "ka" and its symbol is a sideways "K"
--

is "a" and its symbol is an upside down "A"
--

is "ku" and its symbol is a "u" and a "k"
fused together on an edge.
