Unfortunately you cannot assume the encoding, so it's more or less
undefined. The ICCCM however states:
"The WM_NAME property is an uninterpreted string that the client wants
the window manager to display in association with the window (for
example, in a window headline bar).
The encoding used for this string (and all other uninterpreted string
properties) is implied by the type of the property. The type atoms to
be used for this purpose are described in section 2.7.1."
And all implementations use STRING as far as I can tell, which the
ICCCM describes as:
"STRING as a type or a target specifies the ISO Latin-1 character set
plus the control characters TAB (octal 11) and NEWLINE (octal 12). The
spacing interpretation of TAB is context dependent. Other ASCII control
characters are explicitly not included in STRING at the present time."
