In this particular customer project, they have 2 companies operating in China and Taiwan. China uses the simplified Chinese – Sim Sun and Taiwan uses Traditional Chinese – Ming lu. They want to see the standard reports in these respective language forms. I have already configured things for China - where the language is ‘Chinese - simplified (zh)’ with a compatible font (SimHei) and everything is working fine. 

The issue I am having is that China does use the zh language code and reading into the ISO standards zh is used for both simplified and traditional by adding the sub-fixes CN and TW. IFS currently has the simplified zh language added and in the RFC 3066 code loaded as zh-CN for China as it should be. My problem is that we cannot use the zh twice as the language to get a RFC 3066 code of zh-TW loaded which should be Traditional.

I tried to add the traditional Chinese language using zh and it will not allow me to enter it twice.

How do I get IFS to load both fonts with the same language zh?
