Strange results while working with forms

[st]

When I trying to submit a certain text by web form (specifically, TEXTAREA element), some none-ASCII letters are submitted like ä sequences (and so they are retrieved later). But those letters look normal when being entered to text field. Web-server which processes this form doesn't modify acquired data in any way. What can cause this

When I trying to submit a certain text by web form (specifically, TEXTAREA
element), some none-ASCII letters are submitted like ä sequences (and

entered to text field. Web-server which processes this form doesn't modify
acquired data in any way. What can cause this issue?

Type on the form. Do not use Word and then paste into the form.
