In the Rust case, strings (here mere string slices) know the number of UTF-8 code units they contain. Now, Rust has the benefit of learning from languages that came before it. Type 'help', 'copyright', 'credits' or 'license' for more information. Python 3 split, among other things, to Get Unicode Right. Haha, right? Well, youвЂ™ve been told that the Python community suffered the Python 2 vs. LetвЂ™s try JavaScript console in Firefox: 'рџ¤¦рџЏјвЂЌв™‚пёЏ'.length = 7 'рџ¤¦рџЏјвЂЌв™‚пёЏ'.length = 7 evaluates to true as JavaScript. Python 3вЂ™s approach is unambiguously the worst one, though. In this post, I will try to convince you that ridiculing JavaScript for this is less insightful than it first appears and that SwiftвЂ™s approach to string length isnвЂ™t unambiguously the best one. length of a string containing an emoji results in a number greater than 1 (typically 2) and then proceeds to the conclusion that haha JavaScript is so broken-and is rewarded with many likes. (cmd_stdout_bytes, cmd_stderr_bytes) = municate('дЅ еҐЅ'.encode('utf-8'))Д¬md_stdout_code('utf-8'), cmd_stderr_bytes.ItвЂ™s not wrong that 'рџ¤¦рџЏјвЂЌв™‚пёЏ'.length = 7 ItвЂ™s Not Wrong that 'рџ¤¦рџЏјвЂЌв™‚пёЏ'.length = 7 But ItвЂ™s Better that 'рџ¤¦рџЏјвЂЌв™‚пёЏ'.len() = 17 and Rather Useless that len('рџ¤¦рџЏјвЂЌв™‚пёЏ') = 5ДЇrom time to time, someone shows that in JavaScript the. With codecs.open('/tmp/asdf', 'w', encoding='utf-8') as f:ДЄlternatively, you can use raw mode for file I/O: with open('/tmp/asdf', 'wb') as f:ДЇor IPC with subprocess, you must not use universal_newlines=True, as that will always attempt to encode/decode using the system locale. In Python 2.x, you can use codecs.open: # Python 2.x With open('/tmp/asdf', 'w', encoding='utf-8') as f: On the other hand, you can explicitly set the encoding used during I/O in your Python code.ДЇor file I/O, in Python 3.x, you can set the encoding argument of open: # Python 3.x In fact, itвЂ™s probably a good idea to add the export line to your ~/.bashrc, or follow however your Linux distro decides locales should be set. Or # Set locale for current shell session. The simplest solution is to set the system locale, either just for the Python program or for your shell. In my case, the chroot jail yielded: $ locale The downside is that your Python code that runs fine on one machine can fail mysteriously on a different machine. The advantage is that, if your system locale is set up correctly, everything just works - thereвЂ™s no explicit encoding/decoding between strings and bytes. It turns out that Python str's are encoded to/decoded from raw bytes during I/O ( print, file I/O, IPC, etc) using the default system locale encoding.
