This issue might be related to the weird behaviour of xetex I have found:

\toks0{유
술
}\showthe\toks0
\bye

$ xetex test.tex
This is XeTeX, Version 3.14159265-2.6-0.99992 (TeX Live 2015/dev)
(preloaded format=xetex)
 restricted \write18 enabled.
entering extended mode
(./test.tex
>  \par .
l.5 }\showthe\toks0

?
 )
No pages of output.
Transcript written on test.log.

As shown, characters `유' and `술' are gone away and nothing is printed.
Note that Unicode codepoints of these characters are U+C720 and U+C220
respectively, with 0x20 in their lower bytes.
