Script shell echo result of command has unknown values

I try to echo the result of a command. But my problem is that the result has strange values at the end and I can not delete them.

My result after the command is for example:

fnRead 

results to 12. Juni 13:32:18 2028 þ§

But I only need 12. Juni 13:32:18 2028 because I want to check the equivalence of two strings

My code that generates this output is a function:

fnRead() {
    echo $(cat /dev/rtc)
}

I tried to cut off the last strings but it will only remove numbers from the year.

Im working with shell scripts by the way.

According to documentation, you need to use hwclock to read/write from /dev/rtc. You are seeing a raw output of this interface.
