Answer 1

In .htaccess
The text file itself is naturally encoded in UTF-8

Answer 2

Enter the text into the database, from where you can also get it via ajax , just set the encoding to utf8 there.
If this does not suit you, then put both the .txt file and the file in which the utf8 encoding code can help
