This character is a Other Number and is commonly used, that is, in no specific script. The codepoint represents the digit7.
The glyph is a superscript version of the glyph Glyph for U+0037Digit Seven. It has no designated width in East Asian texts. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. The word that U+2077 forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
In arithmetic and algebra the seventh power of a number n is the result of multiplying seven instances of n together. So:
n7 = n × n × n × n × n × n × n.
Seventh powers are also formed by multiplying a number by its sixth power, the square of a number by its fifth power, or the cube of a number by its fourth power.
In the archaic notation of Robert Recorde, the seventh power of a number was called the "second sursolid".
