   Type of modification: Toolkit customization

 DCMTK_ENABLE_ICONV_PASSTHROUGH
   Affected: oficonv
   Type of modification: Activates feature
-  Explanation: If compiled with this macro, the oficonv libary will
-    simply copy input to output during a character set conversion if
-    input and output encoding are the same. This is more efficient, but
-    means that in invalid byte sequences in the source will remain
-    undetected and copied to the target, whereas the default behaviour
-    would detect this and stop the conversion. It is also incompatible
-    with the behaviour of the GNU iconv library.
