If a template is opened with incompatible encoding (such as unicode text but no UTF-8 identification on PY2, or potential encoding mismatches on PY3), a Unicode error will be raised that notes the offending character position but no line is identified.
A potential way to address this is to return a mako.exceptions.RuntimeException that includes the debug information and the original exception.
