sql - Special superscript characters -

how insert string super script characters in postgresql?

i want insert "tm" power of string "rach"? tried following query:

update contact set name=e'rach$^'tm id='10782' 

i don't know if possible convert symbols supersripts without creating mapping function that, can write manually:

update contact set name='rachᵀᴹ' id='10782'

mapping function this:

create or replace function superscript(data text) returns text $$ declare    ss text[];    lt text[]; begin    ss := '{ᴬ,ᴮ,ᴰ,ᴱ,ᴳ,ᴴ,ᴵ,ᴶ,ᴷ,ᴸ,ᴹ,ᴺ,ᴼ,ᴾ,ᴿ,ᵀ,ᵁ}';    lt := '{a,b,d,e,g,h,i,j,k,l,m,n,o,p,r,t,u}';    in 1..array_length(ss, 1)    loop        data := replace(data, lt[i], ss[i]);    end loop;    return data; end; $$ language plpgsql;
