Your command seems to be containing an extra unwanted character which is causing this. This can happen if you copy-pasted the command originally from an UTF-8 editor or from a non-plain text source (e.g. a PDF or a word doc with command mentioned in a formatted text). Instead of copy-pasting you should type the complete command on the prompt or just use the plain text source and it should be working fine.
Thanks. I typed the whole command and it worked.
