euc-kr-editor-sanitizer

Sanitize SmartEditor and HTML editor content for EUC-KR environments.

It keeps ordinary EUC-KR Hangul, converts emoji-like Unicode code points to HTML numeric character references, and drops Hangul syllables/jamo that commonly break legacy EUC-KR pipelines.

Install

npm install euc-kr-editor-sanitizer

Usage

import { sanitizeForEucKrEditor } from "euc-kr-editor-sanitizer";

sanitizeForEucKrEditor("<p>가나다 👍 뷁</p>");
// "<p>가나다 &#128077; </p>"

    oEditors.getById["ir1"].exec("UPDATE_CONTENTS_FIELD", []);

    var textarea = document.getElementById("ir1");
    textarea.value = EucKrEditorSanitizer.sanitizeForEucKrEditor(textarea.value);

    elClickedObj.form.submit();
  }
</script>

Notes

This package uses the KS X 1001 two-byte Hangul syllable set as the allowed Hangul syllable list. Modern Hangul syllables outside that set are removed to avoid broken EUC-KR submissions.
