Cyrillic encoding when submitting a form?

Question

Yii

Situation: if you send a file in the form with lines, then they come to the database ??? instead of Cyrillic. If there is no file, then everything is fine. enctype="multipart/form-data" is set, base encoding is correct, incorrect encoding in the post below:



Yii project. In another similar form, the previous ajax developer sends the file in advance, and only then sends a separate input with text. Did he also have such a problem and he bypassed it in this way?
