I think you may leave source code unmodified as "<b>%i</b> objects selected of type %s"
then just modify po file as
msgid "<b>%i</b> objects selected of type %s" msgid_plural "<b>%i</b> objects selected of types %s" msgstr[0] "已選擇類型 %2$s 的 <b>%1$i</b> 個物件" msgstr[1] "已選擇類型 %2$s 的 <b>%1$i</b> 個物件"
that should work and apply to previous version. (i tested on 0.91)
