ASCII character code specification
Version 2.0.0 · Last reviewed 2026-07-28
- Definition
- ASCII maps integers 0–127 to control codes and printable characters. Bytes 128–255 are not standardized ASCII; this page shows the common Windows-1252 (Western European) code page for that range.
- What it calculates
- Decimal, hexadecimal, octal, binary, HTML entity, Unicode, UTF-8, and UTF-16 forms for ASCII and Windows-1252 characters.
- Inputs
- A character, name, decimal code, hex byte (0x41), or HTML entity
- Outputs
- Decimal / octal byte value
- Hexadecimal (00–FF)
- Binary (8-bit)
- HTML entity
- Unicode code point, UTF-8, UTF-16
- Formula
byte = code & 0xFF; hex = byte.toString(16); bin = byte.toString(2).padStart(8,'0')Use the tool above to search and copy encodings. The tables below are the printable reference for ASCII (0–127) and Windows-1252 (128–255).
ASCII vs Unicode vs UTF-8
Topic What it means ASCII 128 characters (0–127). Letters, digits, punctuation, and control codes. Unicode Universal character repertoire; ASCII is the first 128 Unicode code points. UTF-8 Encoding for Unicode. Code points 0–127 encode as a single identical byte—so UTF-8 is ASCII-compatible. Code page Legacy mapping for bytes 128–255 (Windows-1252, ISO-8859-1, CP437, …). Glyphs differ by page. ASCII control characters (0–31, 127)

- Standard ASCII is 0–127 and matches Unicode for those code points.
- Extended 128–255 values here follow Windows-1252, not a universal “extended ASCII”.

- Units
- Dec / Oct: integer
- Hex: two hex digits
- Bin: 8-bit string
- Boundary conditions
- Printable ASCII is 32–126; 0–31 and 127 are control characters.
- Some Windows-1252 slots (e.g. 0x81) are undefined.
- Example
- 'A' → dec 65 · hex 0x41 · bin 01000001 · HTML A · UTF-8 0x41

Frequently asked questions
Key distinctions behind the tool.
How many characters are in ASCII?
Standard ASCII defines 128 characters (0–127). An 8-bit byte can hold 256 values; the upper half is code-page dependent.
What is the ASCII code for space?
Decimal 32, hex 0x20, binary 00100000.
What is the difference between ASCII and UTF-8?
ASCII is a 7-bit character set. UTF-8 encodes Unicode and uses the same single byte for 0–127, so plain English ASCII text is valid UTF-8.
What are control characters?
Codes 0–31 and 127 are non-printing controls (tab, line feed, carriage return, escape, delete, and similar).
Why does € show as 128 here?
In Windows-1252, byte 0x80 is the euro sign. Other code pages map 0x80 differently or not at all. Prefer Unicode U+20AC in modern text.
How do I look up a code quickly?
Use the search box with A, 65, 0x41, or A. Toggle Use octal or switch to Windows-1252 for bytes 128–255.
