Extract Unicode Range

A contiguous block of integer-valued character IDs (e.g. 0370-03FF covers every Greek and Coptic character). Unicode is organised into named blocks like this. The tool keeps any character whose code point falls in any range you specify.

Comma-separated. 0041-005A, 0061-007A keeps both upper- and lower-case ASCII letters. 1F300-1F5FF, 1F600-1F64F, 1F680-1F6FF keeps the three main emoji blocks. Whitespace around commas and dashes is ignored. Each range can be a single code point (41) or a range (0041-005A). Overlapping ranges are merged.

Twenty-two named Unicode blocks and useful subsets: Basic Latin, Latin-1 Supplement, Latin Extended-A, Greek and Coptic, Cyrillic, Hebrew, Arabic, Devanagari, CJK Unified Ideographs, Hiragana, Katakana, Hangul Syllables, Emoticons, Misc Symbols & Pictographs, Transport & Map, Supplemental Symbols, Regional Indicators, an “all emoji blocks” mega-preset, ASCII printable, digits only, and ASCII letters only. Pick one to fill the range box, then edit if needed.

Flips the filter: characters NOT in any of the specified ranges are kept; matching characters are dropped. Useful for “remove all emoji” (invert with the all-emoji-blocks preset) or “strip Greek letters from this document” (invert with the Greek preset).

It iterates by Unicode code point (using for…of), not by JavaScript UTF-16 code unit. So emoji (which span two code units / one code point) and other astral-plane characters are tested as single units and won’t be split. The stats line shows the total code-point count, not the JavaScript string.length value.

Unicode officially uses hex code points (e.g. U+0041). Every reference table, every standard, and every search you’ll do uses hex. The tool tolerates a leading U+ in case you paste from a chart. Decimal isn’t supported on purpose – it’s confusing and not idiomatic for Unicode work.

The filter is O(input length × range count) where range count is usually ≤ 5. Hundreds of thousands of characters finish instantly. Millions of characters might briefly pause the page; the 200 ms input debounce keeps live typing smooth even at that scale.

No. The page loads three static files (HTML, CSS, JS) and then runs entirely in your browser. Your text never leaves the device – no fetch, no XHR, no analytics, no cookies. You can disconnect from the internet after the page loads and the tool still works.
