Zero-width space. The zero-width space (. . ), abbreviated ZWSP, is a non-printing character used in computerized typesetting to indicate word boundaries to text-processing systems for scripts that do not use explicit spacing, or after characters not followed by a visible space after which there may be a line break .

For example, a space character ( U+0020 SPACE, ASCII 32) represents blank space such as a word divider in a Western script . A printable character results in output when rendered, but a ...
Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [2] [3]
In the narrowest sense, a control code is a character with the general category Cc, which comprises the C0 and C1 control codes, a concept defined in ISO/IEC 2022 and inherited by Unicode, with the most common set being defined in ISO/IEC 6429. Control codes are handled distinctly from ordinary Unicode characters, for example, by not being ...
Hidden text. Hidden text is computer text that is displayed in such a way as to be invisible or unreadable.
