In groff, Heirloom Doctools troff, and neatroff, the `\~` escape sequence produces an adjustable (paddable) but unbreakable space. mandoc, which does not perform adjustment or render to typesetters, supports the escape sequence as a synonym for `\ `, the same as `\0`. This extension is of long pedigree: groff has supported it for at least 30 years, Heirloom for 17, mandoc for 13, and neatroff for 6. Do the same as mandoc to prevent mis-rendering of documents using this escape sequence. Heirloom Doctools troff, a descendant of Documenter's Workbench troff, would be a good place to look for a compatible implementation of the adjustable semantics for this sequence.
