In the Yocto distro that I am using, iconv is supposed to be part of glibc but for some reason it was missing some of the encoding support including UTF-16LE.
Following the instructions found here (http://gumstix.8.x6.nabble.com/iconv-glibc-and-Yocto-td4970038.html) to include incov support worked and this fixed the issue with MM.
Thanks for your help!
