The inverted question mark ¿, and inverted exclamation mark ¡, are punctuation marks that start, respectively, interrogative and exclamation sentences (or clauses) in writing in some languages, such as Spanish (called as signos de interrogacion and signos de exclamacion).
Angle brackets ⟨ ⟩, also known as pointy brackets, triangular brackets, diamond brackets, tuples, chevrons, guillemets, broken brackets, brokets, (often substituted informally by less-than < and greater-than signs >) are used in different areas, for example:

A currency symbol or currency sign is a short designation for the name of a currency. It can be a letter, letter combination, hieroglyph, syllable, special sign or symbol, other varieties of graphemes, graphic abbreviations, abbreviations (including in the form of a letter code), conventional letter designations, as well as their combinations.

Aligning words and sentences in contracts, agreements, and other formal documents using multiple spaces and default tabulations is an ill practice. In proportional fonts, like Times New Roman symbols have different widths, and it is hard to align numerous lines with spaces or tabs precisely. Defining a custom tab stop in Microsoft Word is a precise and straightforward alternative to counting spaces and tabs.
