Next stupid question:

---
It must not contain any stateful bidirectional format characters.

    That is, no [:bidicontrol:] except for the LRM, RLM, and ALM, since the bidirectional controls could influence the ordering of characters outside the quotes.
---

We don't have the :bidicontrol: regexp class.  Do we have another way to
classify bidi control characters?  The have class Cf, but so does many
other non-bidi control characters...
