+Subject: [PATCH] MakeHeader: open files using binary mode
+
+By default, open(sys.argv[1]) use Unicode mode.
+The readlines() will try to convert with the default codec
+(which depends on the i18n settings, so 'ascii' under
+LC_ALL=C)
+
+Open files using binary mode so no conversion will be done
+by readlines(). But then, normal strings can't be used in
+the rest of the code; either all strings have to be prefixed
+with b'' or (simpler) the read line has to be converted to
+a unicode string by calling decode() on it.
