I expect it is terribly inefficient for long spans of text in particular 
language. Command should not be per-character, preferably per-paragraph 
or at least per-word

"([\u{e000}-\u{f8ff}]+)"

However maybe you just do not use sequences of symbols from private use 
area.

I think that low level implementation in browser or in some underlying 
library is much faster
