There are two pitfalls that we need to consider when setting the Exif user
comment (Exif.Photo.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\0\0\0". The actual comment follows after this code.
Note: There is a more simple Exif tag for the title of an image. It is a
20 byte string (type ASCII) and does not store two-byte characters.
(Exif.Image.ImageDescription)
