在CFA网站上报名时姓名用的是拼音，收到ACCEPTANCE LETTER时看见信上说姓名要和官方证件上列示的一样

You should also check your name as shown
above to make sure it is identical to the name printed on your
government-issued photo identification. If it is not the same, please
submit the Name Change Form located at
http://www.cfainstitute.org/aboutus/forms/.

可是在CFA网站的NAME CHANGE FORM 上看到提示说不能接受非英语的字符。

所以请问是否可以用拼音表示姓名，在考场验证身份时会不会遇到障碍？如要改为中文要如何做法？谢谢！
