What Binary / ASCII / Unicode Character Table does, with a checked example
This is a lookup table for character codes. It maps printable characters, control codes, and Unicode code points to their decimal, hexadecimal, and binary representations. You can browse the table, search for a specific character or code, and copy any code value to your clipboard with one click. The most common surprise is that ASCII only covers 128 code points; anything above 127 is part of extended ASCII or Unicode, and the binary representation you see reflects that code point, not the UTF-8 encoding of the character.
Worked example
A concrete input and expected output from the current implementation.
->
Expected output
Decimal: 65, Hexadecimal: 0x41, Binary: 01000001, Unicode: U+0041 LATIN CAPITAL LETTER A
The letter A is the 65th code point in ASCII and Unicode. Its binary form is 01000001 because 65 in binary is 1000001, padded to 8 bits.
