...S4 which limits my resolution per character. I've also limited the maximum range to the lower end of the unicode reserved range 0xD800 however once I build a list of allowed characters and a filter to avoid them I can theoretically push the required number of characters as low as 70-100 for the logo...

You can wrap the above in list if ...
