+      There are two pitfalls that we need to consider when setting the Exif user
+      comment (Image.UserInfo.UserComment) of an image:
+
+      First, the type of the Exif user comment tag is "undefined" (and not
+      ASCII) according to the Exif standard. This means that in Exiv2, we have
+      to deal with a DataValue (and not an AsciiValue). DataValue has the usual
+      two read methods, however, the one taking a const std::string& buf expects
+      the string to contain a series of integers (e.g., "0 1 2") and not a text
+      string. Thus, we need to use the read function that reads the value from a
+      character buffer of a given length.
+
+      Second, the Exif comment field starts with an eight character area that
+      identifies the used character set. For ASCII, these eight characters are
+      "ASCII
