Limitations
Unicode is not supported in RFB versions 3.x and lower so it is impossible to transfer clipboard text outside the Latin-1 character set.
The VNC protocol is pixel based. Although this leads to great flexibility (i.e.- any type of desktop can be displayed), it is often less efficient than solutions that have a better understanding of the underlying graphic layout like X11 or Windows Remote Desktop Protocol. Those protocols send graphic primitives or high level commands in a simpler form (e.g., "open window"), whereas RFB just sends the raw pixel data.
