Wow.  Your enter key seems to be broken.

Would you have used "
   DEF:a=some.rrd....
   DEF:b=other.rrd....
   DEF:1=db.rrd.....
   CDEF:c=a,1,+
"

do you expect c to be equal to a plus the number 1, or to a plus the content
of DEF 1 ?

I think no one considered all numeric to be valid.  Not because it was
described somewhere, but because it is error prone.  _you_ may never use
CDEFs as I did in my example, but that example shows why it was a bad
idea to use numeric names even in version 0.99.x

And in version 1.2 you can, indeed, do "LINE:1#FF0000:line at 1".

I'm sure not all problems are ironed out.


As for the font/encoding problems, I do seem to recall this being discussed
on the developers list quite some time ago.  Please search the archives.
No, I do not remember exactly and no, I do not know.
