+## 11_unknown_encoding.dpatch by Andreas Henriksson <andreas@fatal.se>
+##
+## All lines beginning with `## DP:' are a description of the patch.
+## DP: In case of an unknown/invalid encoding, id3_parse_string() will
+## DP: return NULL, but the return value wasn't checked resulting
+## DP: in segfault in id3_ucs4_length().  This is the only place
+## DP: the return value wasn't checked.
