It can display Traditional Chinese in my all Radio stations, no issue, but I saw it already translated all English phrases into Traditional Chinese in Language Resource File (see below "How to Localize the SoundBridge instrution" which provided by Roku)
" Page 3 of 7, In the Configuration page, there is a Language section, and there is a link that says "View Current Language Resource File". You can either click this link and then save the page,or right-click (control-click on the Mac) the link to save the link to a file.
Later, after you have edited the file, you will come back to the Configuration web pageand use the "Browse" button to select your edited file, then click Update to load the file to
the SoundBridge. "
Based on above intruction, you can see Traditional Chinese translated by Roku in the file, but cannot see it from drop menu in the web config page.
so I expect it can show Tradtional Chinese character in the Roku M1001 web pages and Roku M1001 player.
Hope above info is sufficient.
