[Rüdiger Sonderfeld]

Unicode provides BALLOT BOX* symbols to represent check boxes.

* lisp/net/eww.el (eww-form-checkbox-selected-symbol): New
  customizable variable.
  (eww-form-checkbox-symbol): New customizable variable.
  (eww-form-checkbox): Use `eww-form-checkbox-selected-symbol' and
  `eww-form-checkbox-symbol'.

bug#15707: [PATCH 5/8] EWW: Option to always use external-browser for certain content.

[Rüdiger Sonderfeld]

Emacs can not display videos and has only limited audio support.
Therefore it makes sense to call an external browser for links of that
kind.  This is also a problem because shr turns <video> and <audio>
tags into links to the media.

* lisp/net/eww.el (eww-use-external-browser-for-content-type): New
  customizable variable.
  (eww-render): Handle `eww-use-external-browser-for-content-type'.
  Use \\` to match beginning of string instead of ^.

This seems very specific just for eww... maybe it should just use the recently
added `prettify-symbols-mode'?

`prettify-symbols-mode' only works with font-lock-mode and it would be 
complicated to determine whether the [ ] or [x] are input-elements or literal 
text.  (Or can `prettify-symbols-mode' also match properties?)

Ah, OK, I see.  But it seems like kind of the same ideas, so maybe a
generic facility would be useful... not a font-lock interaction, but for
keeping the record of "this string maps to this Unicode symbol"?
Basically a big hashtable with some user control.  Then
`prettify-symbols-mode' could use that facility too.

RS> and it would be complicated to determine whether the [ ] or [x] are
RS> input-elements or literal text.  (Or can `prettify-symbols-mode'

It can't, but this theoretical generic facility could filter by property
as well, not just by string. Something like:

(setq output (generic-unicode-symbol-replace "input-string-with-properties"))

and the record would be: key "[]", value: '(:symbol unicode-checkmark :properties (...))

I'm just thinking out loud.  Sorry if this looks like overengineering
the problem, but it seems to me that this would be generally useful.

Oh, for example Gnus has special functionality to draw the thread trees.
Users like to control that kind of customization.

Another example: I would use ◐◑◒◓◔◕ in many places that show progress if
I could.  But perhaps that's too arcane :)

I think it'd be easier to go the other way around: provide an
replacement to use if/when the display font doesn't provide a glyph for
that characters.

That doesn't help with drawing trees in Unicode, for example.  What I'm
suggesting is more like an installable icon set.  The user would be able
to say "install my personal tree glyphs and checkbox glyphs and box
drawing glyphs" and all code using the proposed facility would pick up
the user's preference for tree and checkbox and box glyphs.

For a typical use case that a package has implemented ad-hoc, see

I think this case is quite different: none of the proposals so far can
handle it.  And I don't think it can be handled purely locally
(i.e. without knowing that those chars are put together to represent
a tree).

OK.  My proposal is to do something about that need at the Emacs core
level so packages don't have to invent their own glyph mapping
facilities.  Should I take it to emacs-devel or do you want to keep the
discussion here?  And do you agree there's a need?

Move it to emacs-devel.  But if you want it to work for "multi-glyph"
situations (such as trees), then the main problem will be how to
design it.  So, rather than discuss, it might be better to try and come
up with a preliminary implementation.

The situation for EWW (and Custom) is fairly different since relative
alignment is not that important, so the mapping can be done for each
glyph individually, so the system can be fairly simple.

Having a more general mechanism for specifying alternate symbols work be
nice, but since Emacs doesn't have that yet, this is OK, I think.
