Sorry, the error is on the read.  The code I tried to use was:

try	{	lin	=	fil.readLine;	}
catch
{  writefln("File <<" ~ filIter [curFilNdx] ~ ">> is not a valid UTF 
file.");
    fil.close;
    getLine;
   return;
}
finally
{	}
debug (9) writefln ("lin = <<" ~ lin ~ ">>");
try
{ validate (lin); }
catch	(UtfException ue)
{  writefln ("File <<" ~ filIter [curFilNdx] ~ ">> is not a valid UTF 
file.");
    fil.close;
    getLine;
    return;
}

where fil is a File and getLine is one of my routines that automatically 
switches to the next file if the current file has been closed.
