Here are the binary versions of 0 through 10 in decimal: Notice that as the decimal number n increases, you need more significant bits to represent the character set up to and including that number. case-insensitive form following an algorithm described by the Unicode In some areas, it is also convention to use a BOM at the start of UTF-8 This can throw you for a loop because of the way that Unicode tables conventionally display the codes for characters, with a leading U+ and variable number of hex characters. How are you going to put your newfound skills to use? Are you missing a conversion type or found a bug? UTF-8 is one of the most commonly used encodings, and Python often backslashreplace (inserts a \uNNNN escape sequence) and This table summarizes the range or number of bytes under UTF-8, UTF-16, and UTF-32: One other curious aspect of the UTF family is that UTF-8 will not always take up less space than UTF-16.

You can also do . 0x10FFFF (about 1.1 million values, the present at the start of a file; when such an encoding is used, the BOM will be That may seem mathematically counterintuitive, but its quite possible: The reason for this is that the code points in the range U+0800 through U+FFFF (2048 through 65535 in decimal) take up three bytes in UTF-8 versus only two in UTF-16. Its amazing just how prevalent these expressions are in the Python Standard Library. .
