For a Type 1 font you need at least one glyph besides ".notdef", as I
recall (it's been a long time since I worked with Type 1 fonts at that
level!). Actually with Type 1, you could just make a custom encoding
that pointed everything at the same glyph.  Make sure it's monospaced -
e.g. start with Courier, and then you can use the same metrics.

And yes, you can use t1asm or pfatopfb etc, and friends.
