i've made a cab to view chinese, japanese and korean for windows mobile (tested on my Xperia X2 WM6.5.3 and should be working fine with other versions). just install the <East Asian Fonts Support.cab> and do a soft reset. if you want to input chinese, i suggest using baidu input, plumsip or qq pinyin.
if you face difficulties in reading emails and browsing using ie, you may also need to install <Reloadnls.cab> to have the necessary code pages. ce star is using old wince.nls so please do NOT use ce star for your device or you will brick it. since wm6.5.3, the codes pages are no longer saved in registry but in wince.nls. the wince.nls is extracted from a taiwan rom (wm6.5.3) of x2.
please remember to do a full backup before installing the cabs!!
by the way does anyone have the latest wm6.5 rom for Xperia X2? many thanks!
for any issues or problems please feel free to let me know.
