Fl_Help_View list of named HTML entities support

[anmol....@gmail.com]

The complete list of HTML entities are here - https://www.w3schools.com/html/html_entities.asp

Fl_Help_View supports a few - as listed in the help_dialog.html inside the test/ dir

However, some others like the @rarr; are unsupported.

Is there a complete list of supported entities ?

Thanks!

Those are not HTML entities.

These are essentially similar to unicode special characters.

>>>

a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined (built into the markup language) or explicitly declared in a Document Type Definition (DTD). The format is the same as for any entity reference:

&name;

where name is the case-sensitive name of the entity. The semicolon is required.

    Isn't that what's under the heading "Quoted char names" at the bottom of the list I sent?
    e.g. "gt", "quot".. which in the html text would be > " ..

They are indeed. Thanks Greg. I guess the support is indeed partial.

The documentation for Fl_Help_View should be more explicit and changed from:

    "The Fl_Help_View widget displays HTML text. Most HTML 2.0 elements are supported..."

to something more like:

   "The Fl_Help_View widget displays text containing a limited subset of HTML 2.0. It is not a fully feature HTML viewer."
