ASCII 表格

使用方法

1. Scroll the reference table to browse all 128 standard ASCII characters (codes 0–127).
2. Each card shows the decimal code, hexadecimal code, and the character or abbreviation.
3. Control characters (0–31) are shown by their standard abbreviation such as NUL, LF, and CR.
4. Use the table to look up character codes when parsing binary data or debugging encoding issues.

示例

• Character 65 (0x41) is 'A'; character 97 (0x61) is 'a', illustrating the 32-unit offset between uppercase and lowercase.
• Character 10 (0x0A) is LF (line feed) and 13 (0x0D) is CR (carriage return), the two bytes that make up a Windows line ending.
