In your example, the company name will not be translated. However, you should at least make it possible to write the name in the native alphabet. Latin letters look really odd in some other alphabets.
There is also a legal issue: in some countries it is not allowed to use capital letters for anything but some reserved words, in some cases this applies to capital letters in words only. You put your users at risk if you enforce capital letters. That’s one of the many problems with the “capital P” filter in WordPress. :/
