On Unix-like operating systems, text files format is precisely described: POSIX defines a text file as a file that contains characters organized into zero or more lines, [4] where lines are sequences of zero or more non-newline characters plus a terminating newline character, [5] normally LF.
To support specified character encoding, the editor must be able to load, save, view and edit text in the specific encoding and not destroy any characters. For UTF-8 and UTF-16, this requires internal 16-bit character support. Partial support is indicated if: 1) the editor can only convert the character encoding to internal (8-bit) format for ...
The byte-order mark (BOM) is a particular usage of the special Unicode character code, U+FEFF ZERO WIDTH NO-BREAK SPACE, whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: [1] the byte order, or endianness, of the text stream in the cases of 16-bit and 32-bit encodings;
A code point is a value or position of a character in a coded character set. [10] A code space is the range of numerical values spanned by a coded character set. [10] [12] A code unit is the minimum bit combination that can represent a character in a character encoding (in computer science terms, it is the word size of the character encoding).
Kate is a source code editor that features syntax highlighting for over 300 file formats with code folding rules. [ 12 ] [ 13 ] The syntax highlighting is extensible via XML files.

Notepad is a text editor, i.e., an app specialized in editing plain text.

gedit has an optional side pane displaying the list of open files and (in a different tab of the side pane) a file browser. It also has an optional bottom pane with a Python console and (using gedit-plugins) terminal. gedit automatically detects when an open file is modified on disk by another application and offers to reload that file.
