NOTE:
•
An interface description can be a mixture of English characters and other Unicode characters. The
mixed description cannot exceed the specified length.
•
To use a type of Unicode characters or symbols in an interface description, you must install the
corresponding Input Method Editor (IME) and log in to the device through remote login software that
supports this character type.
•
Each non-English Unicode character or symbol (non-English characters) takes the space of two regular
characters. When the length of a description string reaches or exceeds the maximum line width on the
terminal software, the software starts a new line. This may break a Unicode character into two parts and
create garbled characters at the end of a line.
