biblatex-csl-converter/src/unescape-csl.ts

Bibliography format converter: BibLaTeX, BibTeX, CSL-JSON, RIS, ENW, EndNote XML, Citavi, DOCX citations, ODT citations — parse, convert, and export with round-trip fidelity

// If one runs the CSL exporter with escapeText = true, the output from
// citeproc (bibliography and citation entries) will need to be unescaped
// using this function.

export function unescapeCSL(theValue: string): string {
    return theValue
        .replace(/&/g, "&")
        .replace(/</g, "<")
        .replace(/>/g, ">")
        .replace(/'/g, "'")
        .replace(/"/g, """)
