Chemical equation keyboard C

This is a soft keyboard that is convenient for writing chemical equation.
Alphabets for element symbol, numbers, superscript, subscript and symbols for chemical equation can be entered without converting.

You can enter all alphabets for element symbols, numbers from 0 to 9, superscript "⁰,¹,²,³,⁴,⁵,⁶,⁷,⁸,⁹,⁺,⁻,⁼,⁽,⁾,ⁿ", subscript "₀,₁,₂,₃,₄,₅,₆,₇,₈,₉,₊,₋,₌,₍,₎,ₓ", and "+,→,⇄,↑,↓,(,),[,]" for chemical equation symbols.

If you press the key of the alphabet continuously, it switches from uppercase letters to lowercase letters.
The alphabet is a QWERTY array.

Please be aware that superscript, subscript and ⇄ may not be saved properly depending on the character code of the text file to be entered.
If it is UTF-8 of the standard character code of Android OS it can be saved correctly.
There is a possibility of garbled characters when saving with the standard character code of Windows PC.
