That's what the PUA is for. Assign a PUA code point to your special
character, create a font which implements the PUA character, create a
brief "private agreement" which states that this code point refers to
that character and which mentions the font, put the private agreement on
the web, and publish your document with a reference to the agreement.
For most non-professionals, creating the font is the tricky part.

Also see Section 23.5 of TUS.

Note that I am disagreeing with Martin about the PUA being useful only
as a scratch area for standardization.
