I get that error with
#lang scribble/base
For instance, if I want a @(string-normalize-nfd "ä")?
I expect htat I'd get the same error by writing "ä" in decomposed form
in the source (i.e., a sequence of two Unicode code points), but my
mail reader and input methods generate composed forms.

Conceptually you want to signal the error out of the 'parms' computation.
So even if you introduce string->real as a variation on string->number,
you probably want to catch the error it raises and re-cast it as 'params'
message.

Fortunately, one of those casts can be eliminated with a bit of type
annotation on `NUM`. Full code here:

Scribble has a huge but incomplete unicode to latex translation that I extended
a lot for my own purposes, with the ability to handle a few compose characters
like tilde and hat. (Oh, I see scribble does that now too)

What's the proper way to use accented characters in a Scribble

results in the error

There aren't any label-phase expression or expansion positions, so a
transformer will never get the label phase from `(syntax-local-phase)`.
I don't think that a label-phase expansion position would even make
sense, although I'm not completely certain.

What does syntax-local-phase return for the label phase level?

I'm pretty sure that the docs are right in this case.
