Convert string into code symbols by pl/sql - oracle

Question

I have to convert string in my local language into UTF code symbols (I suppose it is UTF code simbols) using pl/sql.
For example the initial string is: "шт", the target string should be шт
Is there any ideas how to that.
Thank you.

Lengthy, but does not depend on server codepage :-)

Are you looking for convert?
select CONVERT('шт', 'AL32UTF8', 'CL8MSWIN1251') from dual
I have not run it, because I am using UTF throuout DB, but you may need to play around with encodings.
