How can I change my passenger's name on my ticket?

[Cindy2]

Dear SBB,

I made the typo while booking the train by misplacing letter o with u of my friend's first name. However, both names are shown on his passport (one with letter u is his real name while the other with letter o is listed under foreign name).

In this case, considering the name under the reservation was shown on the passport, do we need to change the passenger's name?
