which is why latex packages exist ... for the tricky things in life.

if the op doesn't want to use hyperref, then there's always
re-catcoding of the ~ character for the purposes of defining an
argument for this primitive:

{%
  \catcode`\~=12\relax
  \gdef\temp{ text for this game
     url-containing-~-character
     rest of text
  }
}
\expandafter\pdfannotlink\temp

or some such game.  maybe not even the \expandafter is necessary.
