Working with Unicode Characters
On systems that support unicode, named objects on the tree as well as scene annotations can include non-Western (UCS-16) character sets as shown below.

Note | Although Unicode characters (such as µ) can be used for naming user-defined units, they have limited support with functions. Units with such characters cannot be entered in expression fields directly, but can be used in constants within expressions (via < and > operators). For functions that allow specification of both dimensions and units, user-defined units with Unicode characters can be selected from the drop down list. |
