Well, the code is:
// Since LyX uses unicode, also set the PDF strings to unicode strings
// with the hyperref option "unicode". (With Xe/LuaTeX and pTeX,
// unicode=true is the default, with Japanese (platex), the option
// leads to errors (even if the input encoding is UTF-8).)
if (!runparams.isFullUnicode() && !runparams.use_japanese)
opt += "unicode=true,";
That is: LyX outputs unicode itself in some cases, so setting
unicode=false could lead to errors. Still, it might be worth a document
preference on this.
