After spending something like 2 hours on tracking this issue, I finally
found out !!!!

it's as simple as replacing (in src/XmpTagsMetadata.cs):

string stmt_pre_str = stmt.Predicate.ToString();
string stmt_obj_str = stmt.Object.ToString()

by:

string stmt_pre_str = stmt.Predicate.ToString();
string stmt_obj_str;
if (stmt.Object is SemWeb.Literal)
	stmt_obj_str = ((SemWeb.Literal)(stmt.Object)).Value;
else
	stmt_obj_str = stmt.Object.ToString();


Now, the XMP import patch can handle special (read utf8) characters !!!!
