+
+    Always write C code in UTF-8
+    
+    Some people apparently use non-utf8 locales and this caused errors when
+    xcb-proto started using some "fancy" quote marks. Fix this by always
+    using utf8 encoding.

+    DISPLAY starting with / or unix: is always a socket path

+    Improve tutorial example
+    
+    This tutorial example only handles XCB_EXPOSURE and XCB_KEY_RELEASE
+    events and ignores everything else. Thus, there is no point in asking
+    for more kinds of events.
+    
+    A while ago, I ported this tutorial to x11rb [1]. Recently, I received a
+    pull request [2] removing these unnecessary event masks. This commit is
+    thus only partially by me and the 'issue' was originally found by the
+    author of [2].
