✨ Invisible characters

[austincondiff]

Description

We want to provide users with the ability to show invisible characters. In order to do this, our text view needs to support this.

Invisible	Character	Unicode	Name
Space	·	U+00B7	Middle Dot
Newline	¬	U+00AC	Not Sign
Tab	⟶	U+27F6	Long Rightwards Arrow
Return	¤	U+00A4	Currency Sign
Hard Return	¶	U+00B6	Pilcrow Sign
Carriage Return	↵	U+21B5	Downwards Arrow with Corner Leftwards

We should be able to both toggle visibility and customize which character is rendered for the following

• Carriage return (CR)
• End of line (EOL)
• Space
• Tab

Just found out about the project, kudos!

Ideally, "standard" characters (space/tab/CR/NL) could be toggled separate from everything else (hair-spaces, word-joiners, etc., etc.). Personally, I never need/want to see space/tab/newline, but I need to be able to see all the other "invisible" characters (including things that are "visible", as well as be able to tell the difference between characters that are normally indistinguishable from other characters, e.g. no-break-space, no-break-hyphens, etc.).

Probably not first pass, but possibly something to keep in mind down the road?

Thanks for considering!
