I'm narrowing down the issue.

I discovered that correct WM_CLASS is available in openbox/client.c
- client_get_session_ids function. But got =3D
OBT_PROP_GETSS_TYPE(self->window, WM_CLASS, STRING_NO_CC, &ss); returns
true with string array filled with NULLs. Going deeper, I've found that
g_convert function is failing silently. After adding GError I've got the
message: Conversion from character set iso-8859-1 to utf-8 is not supported=
.

Now, my buildroot is quite bare. I didn't bother to check gconv libs copy
and it was it. After adding missing gconv libraries, my
_OB_APP_NAME(UTF8_STRING)
was populated correctly.

For Openbox it would be nice to log some warning that conversion failed,
now it is just silently ignored.

If someone else is having a similar issue, add this to your buildroot
config:

BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_COPY=3Dy
BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_LIST=3D"ISO8859-1 UNICODE"
BR2_GENERATE_LOCALE=3D"C, C.ISO-8859-1, en_US, en_US.ISO-8859-1"
