This time I'm using `GitPython` installed by pypi.\n\nI have this nice tag:\n\n``` python\nIn [8]: tag\nOut[8]: \u003cgit.TagReference \"refs/tags/PROMOTED_1501131729_MKT15_01_12_QU_1\"\u003e\n```\n\nI can get a lot of info out of it:\n\n``` python\nIn [9]: tag.object.hexsha\nOut[9]: u'dca63c5c7e6aab3cd4934e60230ec3419ab87071'\n\nIn [12]: tag.name\nOut[12]: 'PROMOTED_1501131729_MKT15_01_12_QU_1'\n\nIn [13]: tag.object\nOut[13]: \u003cgit.TagObject \"dca63c5c7e6aab3cd4934e60230ec3419ab87071\"\u003e\n\nIn [14]: tag.ref\nTypeError: PROMOTED_1501131729_MKT15_01_12_QU_1 is a detached symbolic reference as it points to 'dca63c5c7e6aab3cd4934e60230ec3419ab87071'\n```\n\nBut this fails:\n\n``` python\nIn [15]: tag.commit\n---------------------------------------------------------------------------\nUnicodeDecodeError                        Traceback (most recent call last)\n\u003cipython-input-15-2431a6e80cf9\u003e in \u003cmodule\u003e()\n----\u003e 1 tag.commit\n\n/home/mdione/local/lib/python2.7/site-packages/git/refs/tag.pyc in commit(self)\n     29         elif obj.type == \"tag\":\n     30             # it is a tag object which carries the commit as an object - we can point to anything\n---\u003e 31             return obj.object\n     32         else:\n     33             raise ValueError(\"Tag %s points to a Blob or Tree - have never seen that before\" % self)\n\n/home/mdione/local/lib/python2.7/site-packages/gitdb/util.pyc in __getattr__(self, attr)\n--\u003e 237         self._set_cache_(attr)\n    238         # will raise in case the cache was not created\n    239         return object.__getattribute__(self, attr)\n\n/home/mdione/local/lib/python2.7/site-packages/git/objects/tag.pyc in _set_cache_(self, attr)\n     54         if attr in TagObject.__slots__:\n     55             ostream = self.repo.odb.stream(self.binsha)\n---\u003e 56             lines = ostream.read().decode(defenc).splitlines()\n     57\n     58             obj, hexsha = lines[0].split(\" \")       # object \u003chexsha\u003e\n\n/usr/lib/python2.7/encodings/utf_8.pyc in decode(input, errors)\n     14\n     15 def decode(input, errors='strict'):\n---\u003e 16     return codecs.utf_8_decode(input, errors, True)\n     17\n     18 class IncrementalEncoder(codecs.IncrementalEncoder):\n\nUnicodeDecodeError: 'utf8' codec can't decode byte 0xa8 in position 108: invalid start byte\n```\n\nUnluckily this is happening with an internal repo and I don't know how to even try to reproduce with a public one. Meanwhile I can workaround it by using `tag.object.hexsha`, which is what I wanted.\n","author":{"url":"https://github.com/StyXman","@type":"Person","name":"StyXman"},"datePublished":"2015-07-30T13:32:03.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":24},"url":"https://github.com/332/GitPython/issues/332"}
