Quotation Value in Line Break Unicode Property
Quotation is a line break class that designates characters used as quotation marks, such as curly quotes, straight quotes, and some typographic variants. These characters are treated as having a specific break behavior: they do not allow a line to break immediately before an opening quote or after a closing quote, but they do permit breaks after an opening quote or before a closing quote in certain contexts. This ensures that quotation marks stay visually attached to the quoted text, preventing awkward line starts or ends with stray punctuation. The class also includes special handling for nested quotes and language-specific conventions, where paired marks like left and right double quotes are distinguished for more precise text wrapping in multilingual content.
