回複：”履“的漢語拚音是 lu。例如姓於的，拚寫為Yu，沒有拚寫為Yv的

What you said "漢語拚音是 lǚ。其中ǚ是韻母，音”與“。電腦打字時為了將ü與u區分，許多輸入方案用筆v鍵輸入ü。" is right. But when you input you should using "lv".

看看周圍的人名就知道，姓於的，英文拚寫為Yu 。有拚寫為Yv的麽？In U.S.A.,The pronunciation of 漢語拚音是from Taiwan or another word from Zhonghuaminguo.The 漢語拚音we are using is mainland漢語拚音 and pronunciation, it had been changed after 1949. It is a long story.
