I just have a tendency to avoid substr() since it always feels like a very expensive call.
substr is actually quite cheap as it doesn't copy the char data from the the original string, it just makes an alias to it. The strings that I am spliting are paths, and because my sub then looks for the place of a slash, which should be 8 bits I don't think so, on UTF8 strings byte offsets and char offsets can be different!
