Yes, there will be problems in search, copy and paste numbers indeed,
even if many string search APIs or algorithms already implement things
like case-insensitive matching, Kana folding, and Unicode

Using the OpenType feature can also solve the input problem, since the
input method does not need to automatically change the code point for
some numbers. (Or the user manually chooses the digits when inputting
them one by one.)
