One can always tell XeTeX to insert a glyph from the current font by its number:
\char64337
for instance. Leave a trailing space (that will be ignored). So your example is
\char64337 \char64338 \char64339 \char64340 \char64341
\char64342 \char64343 \char64344 \char64345
(an end-of-line is the same as a space). Actually the trailing space is really necessary only after the last one.
You can also define a macro for this:
\newcommand{\Ent}[1]{\char#1 }
so you can avoid spaces
\Ent{64337}\Ent{64338}\Ent{64339}\Ent{64340}\Ent{64341}%
\Ent{64342}\Ent{64343}\Ent{64344}\Ent{64345}
or even do it by giving a list of numbers:
\usepackage{xparse}
\NewDocumentCommand{\Entities}{>{\SplitList{,}}m}{\ProcessList{#1}{\Ent}}
\newcommand{\Ent}[1]{\char#1 }
and your input can be simply
\Entities{64337,64338,64339,64340,64341,64342,64343,64344,64345}
