Ascii to unicode converter

World's simplest unicode tool

This online utility converts ASCII characters to Unicode text. Anything that you paste or enter in the input area automatically gets converted to Unicode and is printed in the output area. It supports all Unicode symbols and it works with emoji characters. Created by encoding gurus from team Browserling.

Ascii to unicode converter tool What is a ascii to unicode converter?
This browser-based utility reinterprets sequences of ASCII and ANSI characters as Unicode data. The ASCII encoding uses only 7 bits and supports only 95 printable characters. The most popular Unicode encoding that most browsers implement uses a variable-width encoding from 7 to 21 bits and supports 1,100,000 printable characters. As the simplest characters (a-z, A-Z, numbers, and punctuation marks) use the same amount of bits (7 bits) in both ASCII and Unicode, they are left unchanged in the encoding process. All other Unicode characters are displayed as two, three, or four broken ANSI characters because the ASCII encoding doesn't support multi-byte values. To determine how many bytes each output Unicode symbol uses, we convert the broken input text to binary base and look at the first few beginning bits. This bit pattern tells us how many bytes to consume to create a Unicode glyph. Single-byte Unicode glyphs have the high bit set to zero. What that means is they start with the 0-bit and look like "0bbbbbbb", where "b" is any bit value. So a single byte Unicode glyph matches the same ASCII glyph. Double-byte glyphs start with the pattern "110bbbbb", followed by "10bbbbbb". The total number of free bits in double-byte glyphs is eleven (five in the first byte and six in the second byte). Triple-byte glyphs start with the pattern "1110bbbb", followed by two "10bbbbbb" patterns. In this case, the number of usable bits is sixteen (four in the first byte and six in bytes two and three). Quadruple-byte glyphs start with the pattern "11110bbb" and are followed by three patterns of "01bbbbbb". The total number of bits, in this case, is twenty-one (three in the first byte and six in each of the other three bytes). When we combine these one-, two-, three-, or four-byte sequences together and let the browser decode them to its default encoding, we get valid Unicode characters.

Ralph Waldo Emerson Quote
This example fixes distorted ASCII characters and prints a readable quote by Ralph Waldo Emerson in the output. The quote is written using Unicode's bold-italic letter font that uses 4-byte sequences for each letter. In the broken ASCII text, each letter is represented by four extended ASCII symbols so to restore them, the browser reads four bytes at a time and reencodes these bytes as Unicode. The quote marks and horizontal bar symbol use 3-byte sequences (three ASCII symbols). The author’s name uses simple English letters, which are equally readable in ASCII and Unicode encodings, so the browser doesn't need to reencode them.
“𝑬𝒗𝒆𝒓𝒚 𝒘𝒂𝒍𝒍 𝒊𝒔 𝒂 𝒅𝒐𝒐𝒓” ― Ralph Waldo Emerson
“𝑬𝒗𝒆𝒓𝒚 𝒘𝒂𝒍𝒍 𝒊𝒔 𝒂 𝒅𝒐𝒐𝒓” ― Ralph Waldo Emerson
Rain and Flower Emojis
This example restores broken Unicode emoticons in a short phrase. The destroyed emoticons are printed as three ANSI characters. To restore them, the utility decodes them to binary, extracts the Unicode bits from them, calculates the code point values, and converts them to valid Unicode emojis. The broken sequence "☔" is "☔" ("rain"), and "ðŸŒ" is "🌷" ("flower"), so the phrase is "No rain. No flowers."
No ☔. No 🌷.
No ☔. No 🌷.
Science Lab Equipment
This example looks like Zalgo destroyed it but no, it's not Zalgo, it's just the wrong Unicode encoding. The input text is interpreted as raw ASCII characters but in reality, it's Unicode characters. Because of this encoding mismatch, the text is absolutely unreadable. To understand the input data, it's converted into bytes and encoded to Unicode characters. As a result, we get a list of scientific emojis together with their descriptions in the small-caps Unicode font.
