Typing all seven-segment signs
using only 16 characters of a special font.
A seven-segment sign can be divided into three parts: initial, medial and final. For example:
= + + ;
= + + ;
= space + + , etc.
There are 4 variants of the initial part, 8 variants of the medial, and 4 variants of the final. So we need only 16 characters.

A Unicode interval 2fe0...2fef is free of blocks, at least for September 2019.

U+2fe0 = initial space;
U+2fe1 = initial upper segment;
U+2fe2 = initial lower segment;
U+2fe3 = initial both segments;
U+2fe4 = medial space;
U+2fe5 = medial upper segment;
U+2fe6 = medial central segment;
U+2fe7 = medial upper and central segments;
U+2fe8 = medial lower segment;
U+2fe9 = medial lower and upper segments;
U+2fea = medial lower and central segments;
U+2feb = all three medial segments;
U+2fec = final space;
U+2fed = final upper segment;
U+2fee = final lower segment;
U+2fef = final both segments;
