Can't display Asian Languages HTML Email Templates

We are trying to implement Korean/Chinese/Japanese localizations for our email templates.  Generally, we use html files for the templates but I'm getting some weird behavior when I use the asian character template files.

At this point, I'm making the assumption that NetSuite applies some encoding rules to the file parsing when it converts a template file, which inadvertently screws up the asian language character encoding.

Anyone worked with this issue before or have any advice?  More details below.


I've done quite a bit of research on unicode and charset encodings to resolve the issue.  I've looked into the unix iconv utility and multiple text editor "Save with Encoding" features to ensure that the files are in the correct encoding.  I always double check that the files display appropriately before uploading to NetSuite and I've tried various encodings like SHIFT-JIS, EUC-KR, KSC_5601, KS_C_5601-1987.  I also, tried experimenting with the differences between UTF-8 and the appropriate encodings.
