I have below regex which is used for removing punctuations from a string. What I need is to allow only apostrophes and periods in between words such as “Zipf’s”, “e.g”.
[^\w\s]
CodePudding user response：
An idea to use non word boundaries (where no word-character touches specified characters).
\B matches at any position between two word characters as well as at any position between two non-word characters ...
[^\w\s.’']|\B[.’']\B
