Parameters
text: Specifies the interface description, a string of 1 to 240 characters. The string can include
case-sensitive letters, digits, special characters such as tilde (~), exclamation point (!), at sign (@), pound
sign (#), dollar sign ($), percent sign (%), caret (^), ampersand sign (&), asterisk (*), left brace({), right
brace (}), left parenthesis ((), right parenthesis ()), left bracket ([), right bracket (]), left angle bracket (<),
right angle bracket (>), hyphen (-), underscore(_), plus sign (+), equal sign (=), vertical bar (|), back
slash (\), colon (:), semi-colon (;) quotation marks ("), apostrophe ('), comma (,), dot (.), and slash (/),
spaces, and other Unicode characters and symbols.
When you specify a description, follow these guidelines:
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 in half. This might
result in garbled characters at the end of a line.
