I concatenate some strings created with Integer'Image and print them to 
the screen with Cairo.Show_Text. A subsequent call to Cairo.Status 
returns CAIRO_STATUS_INVALID_STRING. Calling Cairo.Show_Text with String 
literals works fine.

The comments of Show_Text subprogram say that the argument shall be a
"NUL-terminated string of text encoded in UTF-8, or Null_Ptr". Appending 
ASCII.NUL did not help. So what can I do to make the String UTF-8?

I am using the actual Ubuntu repository for Linux and GNAT GPL 2012 for 
Windows, both with libgtkada2.24.
