When can Microsoft provide Sinhalese culture logic?

Have you ever tried to sort a list into ascending or descending order when the locale is not English? probably  you might have not noticed it. Nowadays all the large scale websites are moving towards Unicode compatibility to make the product globalization. However globalization is not just input or output compatibility. 


There are lots of aspects that you need to think of before thinking of making your website Unicode compatible. One such aspect is the support for culture logic. You can make your website compatible for an Unicode language anytime but you might not be able to provide a true globalization experience to your visitors\users if they are outside of the below list. Below is the full list of all the supported cultures we have so far. 


If you use ta-IN culture code you will be able to sort the Tamil letters or words with no issues.  
அஆஇஈஉ


If you use zh-TW it will sort the Chinese letters. Chinese letters are more likely symbols and they differentiate the meaning of the same symbol by making slight changes to it. By using this culture code you can sort these stuff with no issues. I have never tried this code because I could not find the properly listed Chinese Alphabet to check with. 


We do not have Sinhalese in this list. This means you cannot provide a proper sorting option to your users if they are using Sinhalese.
