Based on discussion in PR 660. _PyUnicodeWriter_Prepare() is used incorrectly in unicode_decode_call_errorhandler_writer(), _PyUnicode_DecodeUnicodeEscape() and PyUnicode_DecodeRawUnicodeEscape() in Objects/unicodeobject.c. The second argument is the number of characters that should be reserved after the current position. But in these places the total minimal size is passed to _PyUnicodeWriter_Prepare(). This can lead to allocating more memory than necessary. |

Nice. The only question I have is this is a bugfix or enhancement? Current code seems won't cause any problem but just allocates more memory than needed. |

I think this is a bugfix and should be backported. This is why I made a separate PR rather of suggesting changes to PR 660. |
