Given how this is the same code as above, I think a function would make sense.

+    fileHandle = codecs.open(file, 'rb', encoding='utf-8')
+    print >>outHandle, toCString(os.path.basename(file)) + ','
+    print >>outHandle, toCString(fileHandle.read()) + ','
+    fileHandle.close()
+
   print >>outHandle, '0, 0'
   print >>outHandle, '};'
