About this tool
Converts text to character codes and back, in decimal, hexadecimal, binary or octal. Values above 127 are not ASCII and are shown as Unicode code points, which is normally what you want.
Limitations
- Values above 127 are not ASCII. They are shown as Unicode code points, which is usually what you want.
Questions
- Why is one character several codes?
- Characters above U+FFFF need a surrogate pair in UTF-16, and combining marks are separate code points from the letter they modify.
