negated symbols with \not

[jeisner]

It is common for people to use the \not macro in LaTeX to put a negating slash through a symbol. Perhaps it is a bad habit to write \not\in and \not\exists for ∉ and ∄, instead of \notin and \nexists, but it is a habit nonetheless. So could latex-to-unicode support these as alternative forms?

It may be a little bit of effort to get a comprehensive set of such cases. But here are two excellent ways to look for them:

• most of them are alphabetized under \n in the index of Scott Pakin's Comprehensive LaTeX symbol list.
• most of them contain "NOT" in their Unicode description, e.g., 'NOT AN ELEMENT OF', 'THERE DOES NOT EXIST'.
