- They don't have enough symbols to gracefully handle things like "twist 1 left while simultaneously decreasing one stitch", which comes up more and more with the picture-knit designs I do.
- There's not even a way to distinguish between "cable 2 left" and "twist 2 left" with Xenakis's font.
- The Aire River Design font is *still* not fixed-width. Also, for simpler designs, I like the "it looks like what you end up with" mode of cable charts. The Xenakis font sort of has this, but ARD does not.
- If you use (La)TeX, there's a way to get fonts to be in different colors. And using white for knit, grey for purl makes for (in my opinion) very clear, easy-to-read charts.

(Also, if you've got a way to convey both "twisted make-1 increase" and "knit through the back loop" that does not involve using letters as chart symbols, let me know.)

- Knit

- Purled lifted increase slanting left
- Purled lifted increase slanting right
- Make 3 from 1 increase
- Purled make 3 from 1 increase
- Make 5 from 1
- Make 7 from 1---and do I need symbols for make 4, 6? Do those ever happen?
- K2tog
- SSK/SKP
- P2tog
There will probably be a separate font with wrong-side versions of *everything*, in case you're designing something where both sides are complicated and good-looking. So this list just covers the right side---I'm deliberately not including, say, both p2tog and ssp.

- LCR
- LRC
- RCL
- RLC

- Make 1 from 5
- Make 1 from 7
- Possibly a slightly different make 1 from 3 from the double decreases, that looks more like m1from5.
- Purled make 1 from 3
- Purled make 1 from 5
- Purled make 1 from 7
- Slip one with yarn in front
- Slip one with yarn in back
- Yarn over
- No stitch
- Bobble on 3 stitches
- Bobble on 5 stitches
- Irish knot

Cables

- Cable 1 over 1 left
- Cable 1 over 1 right
- Cable 2 over 2 left
- Cable 2 over 2 right
- Cable 3 over 3 left
- Cable 3 over 3 right
(All six of those need to have both right-side and wrong-side versions.)

- Cable 2 over 1 left
- Cable 2 over 1 right
- Cable 2 over 3 left
- Cable 2 over 3 right
- Cable 3 over 1 left
- Cable 3 over 1 right
- Cable 3 over 2 left
- Cable 3 over 2 right
- Cable 3 over 4 left (?)
- Cable 3 over 4 right (?)
The twist versions (with purl background instead of knit) of all of the above

- Horizontal cable; possibly a different symbol for the last of them.
And all of the assorted mixed cable/increase and cable/decreases I've ever used (of which there are many.)
