cjk - LaTeX Traditional Chinese fonts, numbers in PDF are not searchable

Linux xelatex compile Chinese files with xeCJK.

Fonts Noto Serif CJK TC and Noto Sans CJK TC are able to cover traditional/simplified/pinyin. However, the numbers in the text aren't searchable by PDF viewers (Evince 3.28.4, Adobe Reader 9, Atril 1.20.1). How to overcome it?

Other fonts like WenQuanYi failed with the Pinyin letter 'guǒ'. And AR PL failed in the traditional Chinese letter '爲'.
