The code for generating the representation seems excessively complex in all variations.  
I think it can be shortened to just two branches.  
This is the example for the last implementation, but the equivalent applies to the others as well:

```crystal
if count >= 4 || c == '{'
  into << '{' << c << count << '}'
else
  count.times { into << c }
end

```
