私は十分に夢中になって、この関数を完全ではないにしても、かなり網羅する必要があります:
function removeEncoding(string) {
return string.replace(/À/g, "À").replace(/Á/g, "Á").replace(/Â/g, "Â").replace(/Ã/g, "Ã").replace(/Ä/g, "Ä").replace(/Å/g, "Å").replace(/à/g, "à").replace(/â/g, "â").replace(/ã/g, "ã").replace(/ä/g, "ä").replace(/å/g, "å").replace(/Æ/g, "Æ").replace(/æ/g, "æ").replace(/ß/g, "ß").replace(/Ç/g, "Ç").replace(/ç/g, "ç").replace(/È/g, "È").replace(/É/g, "É").replace(/Ê/g, "Ê").replace(/Ë/g, "Ë").replace(/è/g, "è").replace(/é/g, "é").replace(/ê/g, "ê").replace(/ë/g, "ë").replace(/ƒ/g, "ƒ").replace(/Ì/g, "Ì").replace(/Í/g, "Í").replace(/Î/g, "Î").replace(/Ï/g, "Ï").replace(/ì/g, "ì").replace(/í/g, "í").replace(/î/g, "î").replace(/ï/g, "ï").replace(/Ñ/g, "Ñ").replace(/ñ/g, "ñ").replace(/Ò/g, "Ò").replace(/Ó/g, "Ó").replace(/Ô/g, "Ô").replace(/Õ/g, "Õ").replace(/Ö/g, "Ö").replace(/ò/g, "ò").replace(/ó/g, "ó").replace(/ô/g, "ô").replace(/õ/g, "õ").replace(/ö/g, "ö").replace(/Ø/g, "Ø").replace(/ø/g, "ø").replace(/Œ/g, "Œ").replace(/œ/g, "œ").replace(/Š/g, "Š").replace(/š/g, "š").replace(/Ù/g, "Ù").replace(/Ú/g, "Ú").replace(/Û/g, "Û").replace(/Ü/g, "Ü").replace(/ù/g, "ù").replace(/ú/g, "ú").replace(/û/g, "û").replace(/ü/g, "ü").replace(/µ/g, "µ").replace(/×/g, "×").replace(/Ý/g, "Ý").replace(/Ÿ/g, "Ÿ").replace(/ý/g, "ý").replace(/ÿ/g, "ÿ").replace(/°/g, "°").replace(/†/g, "†").replace(/‡/g, "‡").replace(/</g, "<").replace(/>/g, ">").replace(/±/g, "±").replace(/«/g, "«").replace(/»/g, "»").replace(/¿/g, "¿").replace(/¡/g, "¡").replace(/·/g, "·").replace(/•/g, "•").replace(/™/g, "™").replace(/©/g, "©").replace(/®/g, "®").replace(/§/g, "§").replace(/¶/g, "¶").replace(/Α/g, "Α").replace(/Β/g, "Β").replace(/Γ/g, "Γ").replace(/Δ/g, "Δ").replace(/Ε/g, "Ε").replace(/Ζ/g, "Ζ").replace(/Η/g, "Η").replace(/Θ/g, "Θ").replace(/Ι/g, "Ι").replace(/Κ/g, "Κ").replace(/Λ/g, "Λ").replace(/Μ/g, "Μ").replace(/Ν/g, "Ν").replace(/Ξ/g, "Ξ").replace(/Ο/g, "Ο").replace(/Π/g, "Π").replace(/Ρ/g, "Ρ").replace(/Σ/g, "Σ").replace(/Τ/g, "Τ").replace(/Υ/g, "Υ").replace(/Φ/g, "Φ").replace(/Χ/g, "Χ").replace(/Ψ/g, "Ψ").replace(/Ω/g, "Ω").replace(/α/g, "α").replace(/β/g, "β").replace(/γ/g, "γ").replace(/δ/g, "δ").replace(/ε/g, "ε").replace(/ζ/g, "ζ").replace(/η/g, "η").replace(/θ/g, "θ").replace(/ι/g, "ι").replace(/κ/g, "κ").replace(/λ/g, "λ").replace(/μ/g, "μ").replace(/ν/g, "ν").replace(/ξ/g, "ξ").replace(/ο/g, "ο").replace(/&piρ;/g, "ρ").replace(/ρ/g, "ς").replace(/ς/g, "ς").replace(/σ/g, "σ").replace(/τ/g, "τ").replace(/φ/g, "φ").replace(/χ/g, "χ").replace(/ψ/g, "ψ").replace(/ω/g, "ω").replace(/•/g, "•").replace(/…/g, "…").replace(/′/g, "′").replace(/″/g, "″").replace(/‾/g, "‾").replace(/⁄/g, "⁄").replace(/℘/g, "℘").replace(/ℑ/g, "ℑ").replace(/ℜ/g, "ℜ").replace(/™/g, "™").replace(/ℵ/g, "ℵ").replace(/←/g, "←").replace(/↑/g, "↑").replace(/→/g, "→").replace(/↓/g, "↓").replace(/&barr;/g, "↔").replace(/↵/g, "↵").replace(/⇐/g, "⇐").replace(/⇑/g, "⇑").replace(/⇒/g, "⇒").replace(/⇓/g, "⇓").replace(/⇔/g, "⇔").replace(/∀/g, "∀").replace(/∂/g, "∂").replace(/∃/g, "∃").replace(/∅/g, "∅").replace(/∇/g, "∇").replace(/∈/g, "∈").replace(/∉/g, "∉").replace(/∋/g, "∋").replace(/∏/g, "∏").replace(/∑/g, "∑").replace(/−/g, "−").replace(/∗/g, "∗").replace(/√/g, "√").replace(/∝/g, "∝").replace(/∞/g, "∞").replace(/&OEig;/g, "Œ").replace(/œ/g, "œ").replace(/Ÿ/g, "Ÿ").replace(/♠/g, "♠").replace(/♣/g, "♣").replace(/♥/g, "♥").replace(/♦/g, "♦").replace(/ϑ/g, "ϑ").replace(/ϒ/g, "ϒ").replace(/ϖ/g, "ϖ").replace(/Š/g, "Š").replace(/š/g, "š").replace(/∠/g, "∠").replace(/∧/g, "∧").replace(/∨/g, "∨").replace(/∩/g, "∩").replace(/∪/g, "∪").replace(/∫/g, "∫").replace(/∴/g, "∴").replace(/∼/g, "∼").replace(/≅/g, "≅").replace(/≈/g, "≈").replace(/≠/g, "≠").replace(/≡/g, "≡").replace(/≤/g, "≤").replace(/≥/g, "≥").replace(/⊂/g, "⊂").replace(/⊃/g, "⊃").replace(/⊄/g, "⊄").replace(/⊆/g, "⊆").replace(/⊇/g, "⊇").replace(/⊕/g, "⊕").replace(/⊗/g, "⊗").replace(/⊥/g, "⊥").replace(/⋅/g, "⋅").replace(/&lcell;/g, "⌈").replace(/&rcell;/g, "⌉").replace(/⌊/g, "⌊").replace(/⌋/g, "⌋").replace(/⟨/g, "⟨").replace(/⟩/g, "⟩").replace(/◊/g, "◊").replace(/'/g, "'").replace(/&/g, "&").replace(/"/g, "\"");
}
そのように使用:
let decodedText = removeEncoding("Ich heiße David");
console.log(decodedText);
プリント: Ich Heiße David
PSこれを作るのに1時間半ほどかかりました。
