Makodhi emavara muHTML akakosha pakuratidzira uye kushanda kwewebhu zvirimo mumitauro yakasiyana-siyana nemapuratifomu. Pakati payo, encoding yemavara inotsanangura seti yemavara (mavara, zviratidzo, uye macode ekudzora) anogona kushandiswa negwaro uye kuti aya mavara anomiririrwa sei mumabhaiti. Kukosha kweizvi hakugone kuderedzwa, sezvo ichivimbisa kuti zvinyorwa zvinoonekwa sezvakarongwa, zvisinei nemudziyo kana browser inoshandiswa nemuoni. HTML pakutanga yakashandisa ASCII (American Standard Code for Information Interchange) pakunyora mavara, ayo aikwana kumavara echiRungu. Nekudaro, nemamiriro epasirese einternet, izvi zvakakurumidza kudzikamisa. Kuunzwa kweUnicode uye kuita kwayo muUTF-8 encoding kwakaratidza kufambira mberi kwakakosha. UTF-8 inogona kumiririra hunhu hwese muiyo Unicode seti, iyo inosanganisira anopfuura miriyoni anogona mavara mavara. Izvi zvinosanganisira mitauro yese yakanyorwa iri kushandiswa nhasi, zvichiita kuti ive mhinduro yepasirese kune vanogadzira zvemukati mewebhu uye vanogadzira vachivavarira kuwanda kwekuwanikwa uye kuenderana.
Kutora iyo chaiyo hunhu encoding mumagwaro ako eHTML yakatwasuka asi yakakosha. Kutsanangura UTF-8 encoding mukati megwaro reHTML inova nechokwadi chekuti zvinyorwa zvinomiririrwa nemazvo uye nekunzwisiswa nemabhurawuza pasi rese. Izvi zvinoitwa nekusanganisira meta tag mukati memusoro chikamu chegwaro reHTML, ichizivisa iyo encoding yehunhu yakashandiswa. Tsika iyi haingotsigire kudyidzana nedzimwe nyika nekugarisa mitauro nezviratidzo zvakasiyana-siyana, asi zvakare inodzivirira kubhuroka kwemavara kunogona kuitika kana browser ikasadudzira encoding. Zvakare, kuenderana mukukodhesa hunhu pamapeji ese ewebhu kunodzivirira kukanganisa-ane hukama uye kunosimudzira ruzivo rwemushandisi nekuona kuti zvirimo zvinoratidzwa sezvazvakatarisirwa. Sezvo internet ichiramba ichishanduka sepuratifomu yepasirese, kunzwisisa nekushandisa iyo chaiyo encoding mwero mumagwaro eHTML inoramba iri dombo repakona rekuvandudzwa kwewebhu, kuve nechokwadi chekujeka, kuwanikwa, uye ruzivo rwekutsvaga rusina musono kune vese vashandisi.
