The manual doesn’t, but the docstring for ‘set-fontset-font’ says:

    TARGET may be a script symbol.  In that case, use FONT-SPEC for
    all the characters that belong to the script.  See the variable
    ‘script-representative-chars’ for the list of known scripts.

Following the link to ‘script-representative-chars’ displays several
scripts. Unfortunately, the list is truncated to the first ten
elements with no obvious way to see the whole value. I had to resort
to typing this in *scratch*:

    (let ((print-length nil))
      (insert (pp script-representative-chars)))

After that, I was able to confirm that ‘kana’ is in fact a script symbol.

If you have a buffer with a character you’re interested in, you put
the point before it and invoke ‘describe-char’ (C-u C-x =). Among
other things, it tells you its script.

I think it would help much if:

* There was a link from the manual to the docstring of
‘set-fontset-font’. (I understand there is some ongoing work to
provide such links, in case you use Emacs and Info to read the
* There was a way, looking at the help for
‘script-representative-chars’ with abbreviated value, to expand it to
the whole value. The obvious UI would be to make the abbreviation
ellipsis a button that, when activated, produced the full value.

In practice, though, I use the ‘unicode-fonts’ package. I guess the
politically correct way to refer to it is

    git clone

but I will also mention that it is available from *an* ELPA.
