Since scope of "c" is very wide, and there is even `&c` in the scope, compiler stores the `c` to stack every time on:

  c = PyUnicode_READ(kind, buf, next);

That is the bottleneck.  `if (strict && ...)` is not the bottleneck.

My patch used a new variable with tight scope so compiler can bypass store it to the stack.
