The simplest way to encode a string is using the encode method in the string class. I know this doesn't give us the full picture, so let's explore, one-by-one, the four kinds of exceptions we can find in Ruby.Īll these exceptions share the same parent EncodingError, whose parent is StandardError: What's an encoding error?Īn encoding error happens when our program can't correctly transform the string into its representation with a given encoding. So, when we see a string in our program, we need to keep in mind that, apart from its value, encoding transforms it into a visible representation, mostly in the form of readable characters. It's still valid since UTF-8, the current de-facto standard, grants the same encoding for the first 128 characters. Here, we can see how Ruby transforms each character in the string into 7 bits.ĪSCII was one of the first ways of encoding these characters. If you have a string in your Ruby program, it's translated internally as a sequence of bytes. However, first, we need to understand what they mean and, more importantly, how we can detect them before they happen.Īn additional benefit of understanding encoding errors is that you'll have deeper knowledge of how encoding works and what can go wrong. The good news is that encoding errors are fixable. If you're reading this, it's very likely that you spend a lot of time writing software, so we can try to get ready for encoding errors and leave the cars for later. How do you resolve this error?įor many of us, string encoding is like car maintenance we only think about them when they break. So, you investigate the problem, discover that it's an encoding error, and see some odd characters, such as "�" in the error message. You have thought about all the edge cases of your code, writing unit and integration tests for them, and yet, when you least expect it, you see a notification that an exception occurred.

Note that UNICODE strings have 2 bytes per character and the endianness of the UNICODE data can be controlled using the Little Endian and Big Endian toggles at the bottom of the dialog. These bytes will be displayed as a set of numbers in the Hex, Octal, and Binary fields. If a string or character is entered in the ASCII, EBCDIC, or UNICODE fields, the string will be converted to a set of binary bytes. Note that the endianness of the binary data can be controlled with the Little Endian and Big Endian toggles at the bottom of the dialog (see Introduction to Byte Ordering). The binary data will be displayed as a set of 4 or 8 numbers in the Decimal, Hex, Octal, and Binary fields. If a number is entered into the Float or Double fields, the number will be converted from its floating point value to a binary encoding (4 bytes for a Float and 8 bytes for a Double). See the Introduction to Number Systems for more information on numeric formats. If an invalid number is entered, the other fields will be cleared. The number will be converted into the other three formats and displayed in the corresponding fields. Type a number into either the Decimal, Hex, Octal, or Binary field. Click the ' Tools > Base Converter.' menu option to display the Base Converter window. The Base Converter is an easy-to-use tool for converting between decimal, hexadecimal, octal, and binary numeric formats, plus a number of floating point and string formats.
