A form was submitted in the %S encoding which cannot encode all Unicode characters, so user input may get corrupted. To avoid this problem, the page should be changed so that the form is submitted in the UTF-8 encoding either by changing the encoding of the page itself to UTF-8 or by specifying accept-charset=utf-8 on the form element.
May form na na-submit gamit ang %S encoding na hindi kayang mag-encode ng lahat ng Unicode character, kung kaya't maaaring masira ang user input. Para maiwasan ito, dapat baguhin ang pahina para ang form ay ma-submit gamit ang UTF-8 encoding sa pamamagitan ng pagbago ng encoding ng pahina mismo sa UTF-8 o magbanggit ng accept-charset=utf-8 sa form element.
