NOTE:
• Each Unicode character takes the space of two regular characters.
• To use Unicode characters or symbols in an interface description, install the specific input method editor
and log in to the device through remote login software that supports the character type.
• When the length of a description string reaches or exceeds the maximum line width on the terminal
software, the software starts a new line, possibly breaking a Unicode character into two. As a result,
garbled characters may be displayed at the end of a line.
Description
