You shouldn’t need to know. The engine will use native encoding where possible for efficiency. A lot of the performance improvements between LC 7 and 8 were using the right code paths based on whether the string is native or unicode. > > Suppose I wanted to process a lot of text, so performance is critical.

If it’s text encoded then you probably want to use character offsets and let the engine worry about optimising it. If you know it’s binary data then use bytes.
