* Treat spir-v.xml as utf-8 Treat the input file as utf-8, and configure the XML parser to use the utf-8 encoding. The Chromium build was breaking when trying to parse the XML file as ASCII. * Use Python io.open Try to fix the android-ndk-build flow. It seems to be using an old Python. For example, Python 2.6 builtin function open() did not support the 'encoding' keyword argument. But its io.open method did support it.
