Does mbstring normalize utf-8 strings?

Question

I noticed that mb_convert_encoding always returns valid utf-8, which is great for cleaning up user input, but I wonder whether it will return a normalized form of utf-8 or whether I would have to do that manually after with the \Normalizer class?

Reading the source, mb_convert_encoding does not appear to normalize. It appears to convert between encodings then to substitute illegal characters, and that is all.

Thanks, that's a good idea to look at the source although I probably wouldn't have felt confident in decrypting it... – Jun 21 '16 at 19:23
