See Unicode Blocks "Enclosed Alphanumerics", "Miscellaneous Technical", "Miscellaneous Symbols" (☠☢☣☤) etc.

The best way to do it quickly and system-wide is Compose key (there's even some soft doing this in windoze), just configure what you need (or if you only need it in a Firefox-like browser, use abcTajpu add-on). Something like -
