Hi, which board, which NIOS II program, which UART driver ?

In almost programs for beginner ("getting started", tutorials), every time you send a character to UART, it triggers an interruption and copy it to the Nios II Terminal.

A string is a suite of characters.

So what is the problem ? You want Terminal to print the entire string ? You have to memorize the characters until a Carrier Return is received and after print it to terminal...

Regards.
