/* Note: Encoding strategy
We encode NAME by compound-text and use "COMPOUND-TEXT" in
text.encoding. But, there are non-internationalized window
managers which don't support that encoding. So, if NAME
contains only ASCII and 8859-1 characters, encode it by
iso-latin-1, and use "STRING" in text.encoding hoping that
such window manager at least analize this format correctly,
i.e. treat 8-bit bytes as 8859-1 characters.
We may also be able to use "UTF8_STRING" in text.encoding
in the feature which can encode all Unicode characters.
But, for the moment, there's no way to know that the
current window manager supports it or not. */
