As UTF-8 is an 8-bit encoding no BOM is required and anyU+FEFFcharacter in the decoded string (even if it’s the first character) is treated as aZEROWIDTHNO-BREAKSPACE. Without external information it’s impossible to reliably determine which encoding was used for encoding a string. Each ...

Deciding on data structures is one of the most important parts of building software. As long as you pick the right data structure, the rest of the code will be a lot easier to write. Which of these data structures would be a good way to represent the index for your search engine?
Humans use text. Computers speak bytes.1 Esther Nam and Travis Fischer, Character Encoding and Unicode in PythonPython 3 introduced a sharp distinction between strings of human text and sequences of raw bytes. Implicit conversion of byte sequences to Unicode text is a thing of the past. This...
