There is additional error when paste a group of command

[Leftz]

Hi I use Mobaxtern to add the below a group of commands to a switch 

interface TenGigabitEthernet1/1/1
 description Uplink to Core
 switchport mode trunk
 channel-group 10 mode active

But when I pasted these command, there is additional letter "B" inserted, so that I cannot paste this group of command. When I change Mobaxtern to Putty, I still get the same result. Please see the below.  This kinds of thing once in a while happen, but never have resolve it. Anyone can share some suggestions? Thank you

I have had the experience when attempting to send a group of configuration commands that they are transmitted more quickly than the device can process and buffering issues result. My first suggestion would be to try sending one line at a time. If one line at a time does work then it is a buffering issue and the solution might be something in your emulator to increase the inter character delay or the line feed delay.

Tried it several times. I copied and pasted the below command into text and then copied pasted back to the switch. and i still got an additional letter "B" inserted in the command. finally i found out the space between ip domain name and xxxv.com is not common space. after changed it, it started to work. but i did not check other case so that i am not sure other case(command line) is also like this.

ip domain name xxxv.com

SW1(config)#ip domain nameB xxxy.com
