... resent with patch inline ...
Well... dead keys in winvncviewer 3.3.7 actually do not work and all patches
I found in this mailing list are not satisfactory to me, so I wrote my own
patch to make dead keys OK for me (Swiss french keyboard). I do not have
info about other national keyboards with dead keys, but it should work for
most of them... perhaps some other dead key codes will have to be added.
Please find the patch in attachment. I hope it can help someone... and that
the problem will be fixed in the next release.
