gmt2kml -L with a sting?

Basically I love gmt2kml. 

The output below is probably easier to understand than my question…

===

While

	gmt2kml file.gmt -L8:name,3:lat …

does exactly what I want if there is numeric data in the “gmt” file columns, e.g. lat, lon, time,

	if the column has string, e.g. “DRFT04RR”, then the KML is output with NaN

<Data name = "name">
	<value>NaN</value>
</Data>


is there a way to get a column with a string into the KML ?

I have control of the file input to gmt2kml so I can add quotes, backslashes, or whatever to the string


Thanks,

JJ
