Unicode Inspector Online Free -- Inspect Unicode Characters

Unicode Inspector Online Free — Inspect Unicode CharactersInspect any text for Unicode code points, block names, and character properties online for free. Identify hidden characters and emoji. Free Unicode.How to use Unicode Inspector — step by step

Paste any text — Click the input area and paste any text: normal text, emoji, text from PDFs or Word documents, text that looks "normal" but causes errors in code, or text with unusual spacing. Common uses: diagnosing why copy-pasted text from a PDF fails in a Python string comparison, finding hidden zero-width spaces causing regex failures, identifying look-alike characters in phishing URLs, or inspecting emoji sequences and modifier characters.

Inspect character by character — Every character in the input is listed individually with its Unicode code point (U+XXXX), official Unicode character name, and Unicode block category. Invisible characters — zero-width spaces (U+200B), non-breaking spaces (U+00A0), directional control characters (U+200F, U+200E), and null bytes — are clearly labeled so they are impossible to miss.

Identify the problem character — Use the results to find and remove problematic characters from your text. Copy the clean version or note which characters to strip in your code. Completely free, no signup, handles any length of text.

Frequently asked questionsHow do I find hidden zero-width spaces or invisible characters in text free?Paste your text at tools.arkaserve.com/unicode-inspector — every character including invisible ones is listed with its Unicode code point. Zero-width spaces (U+200B) appear as "[ZERO WIDTH SPACE]", non-breaking spaces (U+00A0) as "[NO-BREAK SPACE]", and directional marks (U+200F, U+200E) as their Unicode names. These invisible characters are common in copy-pasted text from PDFs, web pages, and Word documents, and they cause silent failures in string comparisons, regex patterns, and database queries. Completely free.What is a Unicode code point and why does it matter?A Unicode code point is a unique number assigned to every character in the Unicode standard, written as U+XXXX (hexadecimal). For example: A = U+0041, e with accent = U+00E9, heart = U+2764. Code points matter because two characters can look identical but have different code points — a common source of bugs when copy-pasting text from PDFs or international sources into code. The inspector reveals the exact code point of every character.Why does text copied from a PDF or website cause errors in my code?PDFs and websites commonly use Unicode characters that look like standard ASCII but are not. Smart curly quotes, em dashes, non-breaking spaces (U+00A0 that looks like a space but is not U+0020), and zero-width spaces all cause unexpected behavior in string matching, JSON parsing, and database storage. The Unicode inspector identifies every non-ASCII character so you can clean the text or adjust your parser.
