>> - Indentation codepoint, with no fixed defined graphical representation. For indentation based programming languages.
> That wouldn’t be compliant with existing languages and future languages might use any existing character.
>> -- specific clients may want to show it different (for example as arrows, lines etc., using another color):
> Can’t good editors display tabs in a different color when required ?
Lots of them already do, e.g. Emacs in various modes.

>> --- browsers could let the web page creator let decide the visual representation (character and size) via CSS
>> --- the same with editors, independent from the actual font
>> --- in case of visual impairment, the user could even change the accoustical representation if the editor allows it
>> -- unlike a space symbol, it wouldn't need more than one character per indentation
>> -- unlike tabs or space, it wouldn't be whitespace
>> -- unlike normal arrow characters, one could customize the length in an editor and wouldn't have to insert extra spaces for a better visual imagery
>> - A codepoint for string literal quotes, that would spare one the escaping.
> I rarely escape quotes.
> In a text, I use ’ (U+2019) as an apostrophe and «»“”‘’ as quotes, so I don’t need to escape them.
> When I use PHP to generate some HTML code, I try to alternate simple and double quotes as much as possible. That way I rarely need to escape them.
>> - A statement separator symbol.
> To replace the semicolon in C and the languages based on its syntax?
>> - Other ideas?
> Aren’t you trying to reinvent APL?
>> You may now think, this is highly specific and you are right.
>> However, so are EMOJI signs, in particular those like PINE DECORATION.
>> These days, there are a lot of tools to create small embedded scripting languages and DSLs, which are used in-program in special editors. And there is a lot of people using them.
>> Exactly these could really profit from such a codeblock instead of using conventional ASCII subset characters.
>> Also, there is a lot of potential with really good text editors and IDEs where semantics may matter a lot.
>> Excuse my english, I hope this was understandable.
