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
