add fonts

Hi I am a user of the Kathmandu Pro Theme. I love the idea of changing fonts easily at the theme option. However, my website is built mainly for people reading traditional chinese. Thus, google fonts could not match my needs. I want to add fonts in the option of fonts family, such as microsoft jhenghei which can display correctly in windows OS, . Could you teach me how to do that? Another font, more difficult to add I think, is Noto Sans CJK TC (in google), or Source Han Sans(in adobe). This could not be displayed at windows OS. But it is an open-source font. If I want to use the font in my website, should I upload the whole .ttf to the host? If I did, could I manage the font by the theme option? I know microsoft jhenghei is the easier one to do it. So please help me with that one first... Thank you very Much!
