Currently, PuTTY only allocates 16 bits per character cell to the Unicode code point, which only permits us to represent up to U+FFFF. According to a correspondent (2003), "CJK users will want support for plane 2 (and it's looking more likely that it the ideographs will spill onto yet another plane)".

Update: as of the 2004-10-14 snapshot, PuTTY uses 32 bits internally to store the code point. Platform support for copy/paste and display has some limitations, though.
