Oops, I forgot the remove the reallocation in the unicode case in the patch version 2. Patch version 3: - micro-optimization: group both surrogates cases in the same if to avoid checking 0xD800 <= ch twice - check for integer overflow - (remove the duplication reallocation introduced by version 2) I think that PyUnicode_EncodeUTF8() is more readable after my patch: there maximum if depth is 2 instead of 3, and I removed the goto. It shouldn't change anything about performances for chacters < 0x800 (ASCII and Latin-1), and I expect similar performances for characters >= 0x800.
