List: What method should one use to code whitespace after a period as being sentence-ending, not midsentence, when not employing French spacing? For example, if one writes "... John Doe, PhD. Next sentence x y z ... ." the space in "PhD. Next". In LaTeX, we have "\@. " (code whitespace following puctuation mark as sentence-separating length) and "\ " (code space as intrasentence length) to adjust the magical behavior of ASCII spaces. By experimentation I have found that "Prof.\ Smith" works as expected in ConTeXt but "PhD\@. Next sentence ..." is a nonexistent control code. Prof. Smith % heuristic thinks that the period ends a sentence --- wrong typesetting behavior Prof.\ Smith % coded as space after abbreviation not sentence-separating space --- correct typesetting behavior under English spacing regime versus: PhD\@. Next sentence % Official LaTeX method, nonexistent control References: https://wiki.contextgarden.net/French_spacing Not helpful alas.
