How to correctly execute an Odata query?

Question

PHP

I write in PHP. I execute a cURL request to 1C using the Odata protocol:

http://my.site/buh_from2019/odata/standard.odata/Catalog_Контрагенты

1C responds with an error:

Catalog_Контрагенты" entity is not found

As I understand it, there are some problems with the encoding.
Can you please tell me what to do?

Answer 1

Used a third party library

Answer 2

Work not with KOI-8R, but with UTF-8.
If you can't overcome encodings in PHP, then use urlencode().
