It certainly does for the 7-bit ASCII character set.  That is,
everything works fine if I use o instead of o-dieresis.  As soon as
I replace the o with o-dieresis, that line of text and all subsequent
lines in that text graphic turn into something that looks like
Courier (but only on paper; the display is still correct).

Just for fun, I also tried replacing the o in the Postscript file
with \224 (octal), but in this case the lookup table of characters
isn't in the Postscript file; I wanted to see what would happen,
namely whether I'd get the switch to the Courier-like font, or
something else.  What happened is that the character was simply
left blank.  Not sure what it did for the spacing, given that it's
a proportionally-spaced font.
