Korean & English Braille Converter
The same braille cells can mean different things in Korean and English. Choose the input language to apply core modern Korean letters and contractions or uncontracted English UEB. The supported subset is based on the NIKL 2024 Korean rules and ICEB UEB 2024; it is not a complete implementation of every notation or a certified transcription service.

Frequently asked questions
Does this implement all Korean braille rules?
No. It covers modern Hangul letters, vowel separators and contractions in sections 11–18, ordinary numbers and the supported punctuation listed in the interface. Old Hangul, Hanja, mathematics, music, formatting and mixed Korean/English switching are outside this subset. Unsupported characters and certain ambiguous contexts reject the whole input instead of producing a partial result.
Can I mix Korean and English in one sentence?
Enter them separately for now. Korean mode rejects Roman letters; English mode accepts A–Z, a–z, numbers and its supported punctuation. The interface language and source language are independent choices.
Is English output contracted braille?
English uses uncontracted UEB. Words such as and, for and the keep their letters. Capital and numeric indicators, boundaries before a–j after numbers and supported punctuation are applied. Long uppercase passages use word indicators rather than passage-level optimization.
Why can one character become several braille cells?
A Korean syllable may use initial, vowel and final cells or a contraction. Capital, number and separator indicators can add cells too. The segment table and dot numbers show this relationship. A blank cell is represented by dot number 0.
Can I send the result straight to a braille embosser?
The TXT is UTF-8 six-dot Unicode braille, not BRF, page layout or embosser commands. A screen font does not guarantee physical tactile spacing. Publication or signage needs the target device format and transcription review.
What are the limits and storage behavior?
The maximum is 2,000 characters after NFC normalization; spaces and line breaks are preserved. Some isolated Korean jamo are supported, but jamo attached to syllables and standalone Korean question or exclamation marks are rejected. Input and results remain only in page memory, with no automatic storage or upload.
