Braille Text Generator (Unicode)
指导
Braille Text Generator
Convert any text into Grade 1 (uncontracted) English Braille using the official Unicode Braille block. The tool renders each character as a large 2×3 dot cell so you can see exactly which dots are raised, plus a per-character map showing the source letter alongside its Braille glyph. Useful for accessibility prototyping, classroom demos, signage proofs, and anyone learning the alphabet.
如何使用
- Type or paste the text you want to translate into the input field.
- 切换 Capital Letter Indicator on or off to control whether uppercase letters are prefixed with the ⠠ marker.
- 切换 Number Indicator on or off to control whether digit runs are prefixed with the ⠼ marker.
- Watch the Braille Unicode output update in real time, alongside a visual dot-cell preview and a character-by-character mapping table.
- Copy the Unicode output to your clipboard, or download it as a plain .txt file for embedding in documents and apps.
特征
- Grade 1 Braille translation – Letter-for-letter conversion across A-Z, 0-9, and common punctuation using Unicode Braille (U+2800–U+28FF).
- Large visual dot cells – Each character is drawn as a 2×3 grid of dots so raised positions are unmistakably clear.
- Per-character map – A scannable grid pairs every source character with its Braille glyph and a short label.
- Number indicator support – Digit runs are correctly prefixed with the ⠼ number indicator so they are not misread as letters A-J.
- Capital indicator support – Uppercase letters can be marked with the ⠠ capital indicator (optional toggle).
- 复制和下载 – One-click copy of the Unicode output or download as a .txt file.
- 完全在浏览器中运行 – No text leaves your device; nothing is uploaded.
常问问题
-
How does Braille encode letters as dots?
Each Braille cell contains six dot positions arranged in a 2x3 grid (numbered 1-3 in the left column, 4-6 in the right). Different combinations of raised dots represent different letters, numbers, and punctuation, giving 64 possible patterns including the blank cell.
-
What is the difference between Grade 1 and Grade 2 Braille?
Grade 1 (uncontracted) Braille spells every word out letter-by-letter, making it ideal for beginners and exact transcription. Grade 2 (contracted) Braille uses shorthand contractions and short-form words to reduce space and reading time, and is the standard for published books.
-
Why do Braille digits look the same as letters A through J?
The first ten letters of the alphabet share their dot patterns with the digits 1-9 and 0. A preceding number indicator (dots 3-4-5-6, the ⠼ glyph) tells the reader that the following cells should be interpreted as digits until a space or letter sign resets the run.
-
How is a capital letter marked in Braille?
A capital letter indicator (dot 6, the ⠠ glyph) is placed immediately before the letter to mark it as uppercase. Doubling the indicator (⠠⠠) signals that an entire word should be read in capitals.
-
What is the Unicode Braille Patterns block?
Unicode reserves the block U+2800 through U+28FF for Braille. Each codepoint maps to one of the 256 possible 8-dot Braille cells; the lower 64 codepoints cover the 6-dot patterns used in classic literary Braille. The bits of (codepoint - 0x2800) correspond to dots 1 through 8.
