After that, with the help of the %q format modifier, we get an escaped version of the character. Next, this value is reused in printf with a prefix to get the resulting character.

For each, it uses printf to extract and compare each character with its escaped form.įirst, %o returns the octal form of the character’s code. Hello, does anyone know if you can re-enable ANSI encoding by registry in the notepad, instead of the default UTF8 encoding, which is given since Windows 10 version 1903. The snippet above goes through the first 128 characters in the ASCII table.

The characters we would need to escape in that instance are in the output of the following script: $ for code in " Recall our discussion of writing strings without quotes. Importantly, the difference between these methods is that we interpret or interpolate certain combinations of characters in one context and take them literally in another. They are usually direct, single-quoted, or double-quoted sequences. The standard built-in printf (Print Function) command also has its own special character. In fact, all Bash variables are just strings of characters. Let’s now explore how Bash treats sequences without any quotes. This simply means that we can spread a string over several lines without adding newline characters to it: $ text="a \

enclosing it in single quotes to escape an Windows won't really be fully Unicode if the default Notepad encoding is still the obsolete ANSI code page, but, even if I reluctantly admit changing default behaviors is tricky for compatibility reasons, there should at least be a user option to select the default encoding for new documents, like other third party editors offer, such as Notepad++.

using it at the end of a string or before whitespace characters.

prefixing it with a backslash (which remains, same as with a normal character like ).

Importantly, the is an exceptional character, the special meaning of which can be ignored by:

newline, which is equivalent to under Linux.

”, when we need a double quote within double quotes.

`, also known as the backquote operator.

Fortunately, Notepad is capable of reading UTF-8 files unfortunately, 'ANSI' encoding is still the default. It internally works in UTF-16, and assumes that char-based strings are in a legacy code page. Windows, however, lacks native support for UTF-8. These are all special characters, which may have to be escaped to preserve their literal meaning within double quotes: Most modern (i.e., since 2004 or so) Unix-like systems make UTF-8 the default character encoding.
