How to use Convert UTF8 to Octal
- 1. Paste the UTF-8 text. Type or paste the text you want converted, such as the single letter A, into the input pane.
- 2. Choose a Separator. Enter the character placed between each octal value, matching the format used in a shell escape sequence or a legacy configuration file you are working with.
- 3. Copy the octal output. The output pane shows each byte of your text as a base-8 number. Copy it into a shell script, a legacy config file or a permissions-style annotation.
When to use Convert UTF8 to Octal
Convert UTF8 to Octal shows each byte of a string as a base-8 number, the notation shell escape sequences and some older systems still use for representing characters outside plain printable ASCII. It saves you from converting hex or decimal to octal by hand.
- Writing a shell escape sequence with a special character. You need to embed a specific non-ASCII byte in a shell script using an octal escape sequence, and want to confirm the exact digits before hardcoding them.
- Reading a legacy Unix configuration file. An old configuration format specifies certain characters using octal escapes rather than hex, and you want to translate a plain-text value into that older notation.
- Checking a printf-style octal format specifier. You are debugging output from a printf statement using the %o format for character codes and want a reference value to compare your program's output against.
