Join Unicode

Need to merge lines of Unicode text together cleanly? The Join Unicode tool lets you combine grapheme-rich strings using custom separators while trimming and skipping blank lines. Whether you’re cleaning data or generating formatted text, it gives you full control over how your text joins together.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .log, .csv
Total characters: 0
Options
Trim whitespace
Ignore invalid codes

How to Use:

  1. Paste your Unicode code points into the input box (one per line, like U+0041)
  2. Use Join Mode to choose how characters are separated (none, space, newline)
  3. Toggle Trim whitespace to clean each line
  4. Toggle Ignore invalid codes to skip errors gracefully
  5. Output updates live and flashes when it changes
  6. Use Copy, Export, or Clear buttons as needed
  7. Optionally import from a .txt, .csv, or .log file

Tool Options:

  • Join Mode: Switch between no separator, space, or newline using the radio buttons
  • Trim whitespace: Removes surrounding spaces from each line before parsing
  • Ignore invalid codes: Skips bad lines instead of showing a ? replacement

Example:

Input:

U+0041
U+0062
U+03B1
U+3042

Output (Join Mode: space):

A b α あ

Common Use Cases:

Join Unicode is great when you’re working with character sets, code point data, or exporting Unicode sequences from other tools. Whether you’re reverse engineering a grapheme set or testing how characters render, this tool gives you full control over formatting and output.

Useful Tools & Suggestions:

When combining pieces of Unicode text, Concatenate Text is a natural fit it gives you full control over how things are stitched together. And if the join creates anything unexpected, Convert Unicode to Hex can show you exactly what’s going on under the hood.
