Location ASCII-IPA Table

    I apologize for my very hasty post on this same subject the other day,
but I was in a rush and forgot myself.
    Anyway, I was wondering if there was a site with an ASCII-IPA table so
that I can post a bit of my new language's (as yet unnamed) phonology, and
perhaps a bit of the grammar as well.
    Also, in Silindion, there is an odd consonent that sounds a bit like a
hissed-s, perhaps an apical-s, with the tongue in the same position to say
apical-t but without touching. Very breathy and wierd. I was wonder if anyone
had any idea what this sound is, and if there's a symbol for it. I'm sorry i
can't describe it better, but I haven't heard it in any natlang, and just
thought it up one night long ago.
