QueryTextExtents one-byte and two-bytes wrappers

Hello,


I see that the X protocol includes a QueryTextExtents call that takes a
two-bytes string.

Xlib seems to provide two different wrappers, a direct one called
XQueryTextExtents16 and another called XQueryTextExtents that takes a
one-byte string, inserts zero bytes at odd positions and then calls the
X server.

But libxcb only provides the direct wrapper, seeing from docs and from
proto/src/xproto.xml.  Am I correct?  I happen to need the one-byte
version, how can I do?



Thanks,

Andrea Monaco
