How to add system properties which has "white space" using CLI.

Issue

For example, following is working when I manually edit confiugraion file to add it.

System.setProperty("msg", "Código Inválido");

But using CLI, the white space is automatically gone.

[standalone@localhost:9999 system-property=msg] :write-attribute(name=value,value=Código Inválido)

result ==> CódigoInválido

If double quote is used, the string is broken.

[standalone@localhost:9999 system-property=msg] :write-attribute(name=value,value="Código Inválido")

result ==> C?digo Inv?lido

How to keep the white space?
