Unicode Tools for Inspecting, Combining, and Repairing Characters
These tools work on the actual Unicode mechanism rather than a lookup table: real code point data, real byte sequences, and real normalization. Start with the inspector if something looks right but behaves wrong.
Perfect for
- Identify an unfamiliar character, or find one that is invisible.
- Combine letters into a single character, or build sub and superscript text.
- Repair text whose accented characters arrived garbled.

All unicode tools
Every tool is free, instant, and runs right in your browser — your text never leaves your device.
Underline Text Generator
Underline text with Unicode combining characters for social posts and emphasis. This Underline Text Generator applies combining underline characters to create stylized text that works across platforms.
Try it nowSuperscript Generator
Convert letters and numbers into stylish superscript characters. This Superscript Generator maps characters to their Unicode superscript equivalents for mathematical notation and stylized text. Perfect for superscript and subscript LaTeX-style formatting without needing LaTeX syntax.
Try it nowSubscript Generator
Turn text into subscript characters for formulas and creative copy. This Subscript Generator converts characters to Unicode subscript equivalents for scientific formulas and stylized text. Ideal for superscript and subscript LaTeX-style formatting using Unicode characters.
Try it nowLetter Combiner & Merger
Letter combiner and merger generator — combine letters into one symbol, browse 150+ combined letter characters and Unicode ligatures, or use the formula shorthand to generate any letter combination. Covers combining characters, digraphs, and diacritics: AE→Æ, fi→fi, oe→œ, ss→ß and more.
Try it nowSmall Caps Generator
Generate small caps text instantly for bios, headings, and design copy. This small caps generator converts letters to small-cap styled Unicode output.
Try it nowInvisible Text Generator
Generate invisible text and blank space you can copy and paste. Pick from five empty Unicode characters — Hangul Filler, Braille Blank, Zero Width Space, Word Joiner, and No-Break Space — and see which one works where, so your blank messages, invisible usernames, and empty bios actually go through.
Try it nowUnicode Character Inspector
Paste any text and inspect every character: its code point, Unicode name, block, category, UTF-8 bytes and escape forms. Finds the invisible characters and look-alike letters that make text behave strangely while looking completely normal.
Try it nowUTF-8 Decoder and Encoder
Decode UTF-8 bytes to text, encode text to UTF-8, and repair garbled characters like é or ’ back to what they should have been. Includes Unicode NFC/NFD normalization and precise reporting of invalid byte sequences.

Step-by-step articles that show you exactly how to get the most out of these tools.
Why Pasted Text Has Invisible Characters (And How to Find Them)
Text copied from PDFs, Word and websites often carries zero-width spaces, non-breaking spaces and soft hyphens that break search, forms and code. Here is how to find and remove them.
Subscript Generator for Chemistry and Formulas
A practical guide to subscript text for chemical notation, compact formulas, and short labeled content in plain-text environments.
Underline Text Generator for Instagram and Notes
How underline-style Unicode text works, where it is useful, and how to keep underlined copy short enough to remain readable.
Small Caps Generator for Headings and Bios
Why small caps stay more readable than many decorative styles and where they work best in headings, bios, and short labels.
Common questions
Which Unicode tool should I start with?
The Unicode Character Inspector. Paste the text that is behaving oddly and it will name every character, flag anything invisible, and show the exact bytes — which is usually enough to identify the problem before you try to fix it.
Why does text copied from a PDF behave strangely?
PDFs insert soft hyphens at line breaks and often use non-breaking or figure spaces for alignment. All of these are invisible on screen but break exact-match search, form validation, and code. The inspector finds them and the Text Cleaner removes them.
Do these styled characters work everywhere?
Mostly. Precomposed characters such as Æ and œ render reliably. Combining marks like the underline and strikethrough overlays depend on the renderer, and a few platforms strip them when saving a username — test before committing.
