Convert .otf font into a .gif image of all glyphs

How can I convert a .otf font file into a .gif image, where each glyph within the font occupies a single frame in the gif?

I have seen imagemagick used to convert glyphs into pngs, 

convert -background none -fill black -font font.otf -pointsize 300 label:"Z" z.png

Is this extendable for what I am after?

Or do I need to use a different method?

(Also note that the above command doesn't work properly for me, the font I am using, tangwar-annatar, has some glyphs that were cut off by the edges of the png generated by the above command)

I'm on a mac with access to pretty much everything, so would accept any solution in any language as long as it works for me.

Ok, I have seen your font and the characters seem to extend beyond the expected sizes. I think all you need to do is use a bigger canvas:

#!/bin/bash
{
   for c in {a..z} {A..Z} {0..9}; do
      convert xc:none[1000x1000] -background none -fill black -font tengwar.otf -pointsize 300 \
         -gravity center -annotate 0 "$c" miff:-
   done

   # Do any problematic characters as an afterthought, e.g. semi-colon, and exclamation
   convert xc:none[1000x1000] -background none -fill black -font tengwar.otf -pointsize 300 \
         -gravity center -annotate 0 ";" miff:-
   convert xc:none[1000x1000] -background none -fill black -font tengwar.otf -pointsize 300 \
         -gravity center -annotate 0 "!" miff:-

} | convert -dispose background -delay 20 miff:- anim.gif

Updated Answer

You may get on better with -annotate on a fixed background as below. I have also added how to deal with problematic characters in this example - you can do the same in the other example too:

#!/bin/bash
{
   for c in {a..z} {A..Z} {0..9}; do
      convert xc:none[350x350] -background none -fill black -font arial -pointsize 300 \
         -gravity center -annotate 0 "$c" miff:-
   done

   # Do any problematic characters as an afterthought, e.g. semi-colon, and exclamation
   convert xc:none[350x350] -background none -fill black -font arial -pointsize 300 \
         -gravity center -annotate 0 ";" miff:-
   convert xc:none[350x350] -background none -fill black -font arial -pointsize 300 \
         -gravity center -annotate 0 "!" miff:-

} | convert -dispose background -delay 20 miff:- anim.gif

Original Answer

You can do something like this:

#!/bin/bash
for c in {a..z} {A..Z} {0..9}; do 
   convert -background none -fill black -font arial -pointsize 300 \
   label:"$c" -gravity center -extent 350x350 miff:-
done | convert -dispose background -delay 80 miff:- anim.gif
