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.
Seoladh foirm san ionchódú %S nach gcuimsíonn gach carachtar Unicode, agus seans go mbeadh ionchur an úsáideora truaillithe dá bharr sin. Leis an bhfadhb seo a sheachaint, ba chóir ionchódú an leathanaigh féin a athrú go UTF-8, nó accept-charset=utf-8 a shonrú san fhoirm, sa chaoi go seolfar an fhoirm san ionchódú UTF-8
