 xlsfonts -fn '-adobe-courier-bold-r-normal--18-180-75-75-m-110-iso10646-1'
seems to tell me that the font is available.

However when I select this font via
(set-face-font 'default "-adobe-courier-bold-r-normal--18-180-75-75-m-110-iso10646-1")

The \infty symbol did not change  not change. 

Could  you do an experiment? Download Aidan's pkg

http://www.parhasard.net/xemacs/TeX-escape-region.el
and convert the symbol using the function TeX-escape-region.
And tell us what you see.
