Old Hangul Input Method

This is a Javascript-based IME for typing archaic Korean Hangul letters (e.g. ㅸ, ㅿ, ㅵ) easily in a Unicode-compliant manner. Works in all standards-compliant Web browsers!

How to run

1. Download this repository to your device.
2. Open main.html and start typing

Keyboard layout

Note

• (ㅇ) represents the bottom circular half of the letters ᄛ, ᄝ, ᄫ, ᄬ, ᅗ.
• The [F] key indicates that any consonants typed after it are for the next syllable block. For instance: ᄋ+ᅡ+ᄉ+ᄃ+ᅡ = 앗다, while ᄋ+ᅡ+[F]+ᄉ+ᄃ+ᅡ = 아ᄯᅡ.
• For best results, install the 'Noto Sans CJK KR' sans-serif font - most Korean Hangul fonts do not support archaic Hangul.
  • To try other fonts, open main.html in a text editor. In the line containing font-family: "Noto Sans CJK KR", normal;, replace 'Noto Sans CJK KR' with the name of the preferred font.
  • Some other fonts which support archaic Hangul include 'NanumBarunGothic YetHangul' and 'NanumMyeongjo YetHangul' (both are decent looking but are slightly buggy).
