In IDL 8.1 version, default encoding for workspace and resource file UTF-8.
If we need to support surrogate pair (in Chinese environment), we need UTF-16 encoding.
In UTF-8 encoding surrogate pair character is displayed as '??'.
But we could not change to UTF-16 encoding.
If we change to UTF-16 encoding in IDL workspace file entries got messed up or IDL got crashed.
Also even if we input surrogate pair character in widget_text control, GET_VALUE returns '??'
Please give support for UTF-16 encoding in IDL 8.1 version.
Thanks in advance
