How to text to octal by hand
Each character has a code number. Write that number in base 8 by dividing by 8 repeatedly: 72 ÷ 8 = 9 remainder 0, 9 ÷ 8 = 1 remainder 1, 1 ÷ 8 = 0 remainder 1. Read the remainders backwards and you get 110.
Text is encoded as UTF-8 first, so ASCII characters give one three-digit group each, and characters like é give two (303 251). Choose the separator to match how you will use the result, for example a backslash prefix for string escapes.

Text to octal FAQ
How do I convert text to octal?
Find each character’s code and write it in base 8. H is 72, which is 110 octal.
What is "Hello" in octal?
Hello is 110 145 154 154 157.
Why is the digit 0 equal to 060?
The character 0 has code 48, which is 6×8 + 0 = 060 in octal. It is not the number zero.
What is the octal for a space?
The space character is code 32, which is 040 in octal (4×8 + 0), shown here with three digits.
