Add Config setting to force "lame fonts"

[tznind]

@tznind - I'm trying to figure out why you're not getting the right glyphs for buttons.

With that font, I get:

@tig these are the fonts that I have configured - I havent made any changes I think, so this should be the default fonts if you were to install Visual Studio Community Edition at the time I did (a few years ago now).

These are the missing font characters (tickbox, radio button, button corner etc)

Windows ConHost is simply not capable of rendering correctly.

I suggest you switch to Windows Termianal. You can configure the default behavior in Windows Settings:

Or switch to "Let Windows decide" also works.

Changed name of Issue to something actionable.

We already have the ability to override Glyphs via CM:

But it'd be nice to have a single setting like;

"Application.ForceLameFonts": true,

Extra credit if we can detect the need (I've already thot a bunch about this... it's really hard to get right).

[tznind]

I think having named defaults would be nice.

E.g. GlyphSet then you can override specific runes if wanted in the glyphs bit

So just would be

{
  "GlyphSet": "Lame",
  "Glyphs": {
    "Expand": "➕",
    "Collapse": "➖",
    "Close": "✘",
    "Move": "◊"
  }
}

Just found out that CM is broken for overriding Glyphs.

Working on a fix now.

[tig]

now with

• Fixes #3839, #3922 - CM Glyphs not working #3923

This works:

I think it's best to address this PR by leveraging themes.

In #3923, I'm going to move the Glyphs out of SettingsScope into ThemeScope.

That will fix this issue too; you can do this:

{
    "$schema": "https://gui-cs.github.io/Terminal.GuiV2Docs/schemas/tui-config-schema.json",
    "Theme" : "LameGlyphs",
    "Themes": [
        {
            "With LameGlyphs": {
                "Glyphs.LeftBracket": "[",
                "Glyphs.RightBracket": "]",
                "Glyphs.CheckStateChecked": "✓",
        }
    ]
}
