you may want use json_unescaped_unicode constant

$arr = ['s.n' => 1, 'english_word' => 'test', 'nepali_word' => 'परीक्षण'];  echo json_encode($arr, json_unescaped_unicode);  // output : {"s.n":1,"english_word":"test","nepali_word":"परीक्षण"}

in issue context , when using headers content-type: application/json need set charset follows:

->withheader('content-type', 'application/json;charset=utf-8;')
