SubString

Pop a multi-byte string s₃, get i₁ characters from the position i₂ (1 based) and push the result back on the stack.

The start position is given in characters. This action works properly with international characters.

i₁ is expected to be positive or zero.

Since version 5, the String object substr(), substring() or slice() functions should be used instead.
