unable to filter or search the data in different languages in django

Question

I have posted data(ex:title field) in different languages, when i try to filter the data in get request it is giving empty result

GET /rails: My get request result is :

[
    {
        "id": 1,
        "type": "channel",
        "filter": [
            1
        ],
        "data": [
            1
        ],
        "status": 0,
        "rows": 0,
        "title": "string"
    },
    {
        "id": 2,
        "type": "appgg",
        "filter": [
            2
        ],
        "data": [
            2
        ],
        "status": 1,
        "rows": 2,
        "title": "ಚಲನಚಿತ್ರ"
    }
]

GET /rails?title=string it is giving proper result:

[
    {
        "id": 1,
        "type": "channel",
        "filter": [
            1
        ],
        "data": [
            1
        ],
        "status": 0,
        "rows": 0,
        "title": "string"
    }
]

when i try to filter title data other than english i am getting empty result

GET /rails?title=ಚಲನಚಿತ್ರ:

expected result :

[


    {
            "id": 2,
            "type": "appgg",
            "filter": [
                2
            ],
            "data": [
                2
            ],
            "status": 1,
            "rows": 2,
            "title": "ಚಲನಚಿತ್ರ"
        }
]

Actual result:

[]

when I try to print request params in my django views like below:

title = self.request.query_params.getlist('title',None)
print(title)

I am getting the following log:

title filter �²¨�¿¤Í°

Django is unable to identify the language I am passing, How can I add multi-language support in Django?

Thanks
