Update RegExp to replace \w with PHP equivalent with full unicode
With PHP, \w is equivalent to [\p{L}\p{N}_]+ (which supports different languages). However, that is not the case with JS, where its definition remains constant even with the full unicode flag.
There are still some discrepancies. By switching from JS to PHP, one can see that e.g. the hashtag with Chinese is not a match in JS (i.e. during preview it won't be a hashtag, after posting it will be)
I recommend tagging as
1.0.1.\wwith PHP equivalent with full unicode\wis equivalent to[\p{L}\p{N}_]+(which supports different languages). However, that is not the case with JS, where its definition remains constant even with the full unicode flag.
