Unfortunately, this isn't a complete solution. The purpose of the "escape_xml_chars" function is to escape characters that have special meaning in XML, e.g. "&" -> "&", "<" -> "<" etc. The "xmlcharrefreplace" option on encode() does not do that.
I am surprised that you got this traceback, as the SVG is output using a UTF-8 EncodedFile object, which should be able to handle any unicode characters you throw at it. Can you provide a short, standalone example that reproduces the error, and some information about your platform, so I can examine further? As for your suggestion to encode mathematical characters as unicode, unfortunately that would only partially. In order to layout the mathematical expressions, we must have the same font available at generation and rendering time to know the size of the characters and therefore how to place them next to each other correctly. That said, if you use the STIX fonts (set "mathtext.fontset" to "STIX"), those do use a Unicode-based encoding rather than the arbitrary one used by the Bakoma Computer Modern fonts. Of course, generating a math expression using the STIX fonts and rendering it using a different Unicode math font is not guaranteed to work well -- you are almost certain to get overlapping or misplaced glyphs.
