Unicode 9.0 has added the ISO/IEC/IEEE power symbols (standby, on, off, etc.) to the Miscellaneous Technical block [1]. These characters are pretty useful in e.g. technical documentation, manuals and UI elements such as the GtkSwitch widget. The codepoints are: POWER SYMBOL U+23FB ⏻ POWER ON-OFF SYMBOL U+23FC ⏼ POWER ON SYMBOL U+23FD ⏽ HEAVY CIRCLE U+2B58 ⭘ POWER SLEEP SYMBOL U+23FE ⏾ [1]: http://www.unicode.org/charts/PDF/Unicode-9.0/U90-2300.pdf
I'm working on a new computer language named Wee, that is using DejaVu Mono Sans for operators. In computer science symbol "^" is used for power but also the same symbol is used for xor. Having the power symbol created I could use it for "power" (xⁿ) instead of (x^n). The problem I have arises due to lack of letters for superscript. Only several letters are available not all alphabet letters.
