A Korean–English keyboard typo is text typed with the keyboard set to the wrong language, so Korean comes out as Latin letters or English comes out as Hangul. It happens because a Korean keyboard has Hangul letters on the QWERTY keys and a Han/Yeong key that switches between the two. For example, 한글 comes out as gksrmf, and hello comes out as ㅗ디ㅣㅐ.

What is a Korean–English keyboard typo?
How the Korean keyboard and Hangul syllables work
- The Korean and English layouts share the same keys. The standard Korean layout, Dubeolsik (2-set), puts 14 consonants and 12 vowels on the 26 letter keys, one on each key.
- Shift changes the letter on 7 keys only: the double consonants ㅃ, ㅉ, ㄸ, ㄲ and ㅆ, and the vowels ㅒ and ㅖ. The other 19 keys give the same Hangul letter with or without Shift.
- A Hangul syllable is built from an initial consonant, a vowel and a final consonant. 19 initials × 21 vowels × 28 finals (including no final) make 11,172 syllables.
- Unicode sets the code of a Hangul syllable as 0xAC00 + (initial × 21 + vowel) × 28 + final. 안 has the initial ㅇ (11), the vowel ㅏ (0) and the final ㄴ (4), so its code is U+C548.

Questions about the Korean–English Typo Converter
How does the converter change the text?
It uses key positions. The standard Korean keyboard (Dubeolsik, 2-set) puts one Hangul letter on each QWERTY key. For example, d is ㅇ, k is ㅏ and s is ㄴ. The tool changes each key to the letter in the same position and then builds syllables in the same way as a Korean keyboard. So dkssud becomes 안녕.
How does automatic detection work?
The tool checks each word. A Hangul word that contains single letters, such as ㅗ디ㅣㅐ, changes to English. An English word changes to Korean only when the result contains only common Hangul syllables. Common English words that also make Hangul, such as and or work, do not change. Correct Korean and correct English stay as they are.
Why is the automatic result sometimes wrong?
Short words are ambiguous. For example, the keys g and o make the English word go and the Korean word 해. Korean expressions such as ㅋㅋㅋ and ㅠㅠ are kept, so a short English word that makes the same pattern is also kept. When the result is wrong, choose the direction with the buttons above the text box.
Does it handle double consonants and final consonant clusters?
Yes. Shift keys make double consonants and two vowels: R is ㄲ, E is ㄸ, Q is ㅃ, T is ㅆ, W is ㅉ, O is ㅒ and P is ㅖ. Two keys make clusters such as ㄳ, ㄺ and ㅄ. When a vowel follows, the last consonant moves to the next syllable. So ekfrdl becomes 닭이.
What does the converter leave unchanged?
Numbers, punctuation, emoji, line breaks and spaces stay as they are. Web addresses and email addresses also stay as they are in every direction. You can paste several paragraphs at one time.
Is my text sent to a server?
No. The conversion runs in your browser. The text is not sent to a server and is not saved. Do not paste passwords or other secret text into any web page.
