Hi guys!
Thanks a lot everyone here. After trials and re-testing based on your
comments and suggestions, finally I've the labels come up! Great!
However, I've problem remain to be resolved: there are Chinese (or you
treat it as Unicode) characters in the DGN map don't show up correctly
(appears as garbage characters).
Is it an inherent problem when using DGN file with MapServer? Or
anybody can help?
Thanks a lot.
