How to remove all characters except alpha numeric in text column
The column is populated with data that contains quite a few Unicode characters. The rows of interest to me are the ones where the characters are only in the range of a-z (upper or lower case) or 0-9. To me, the replace functionality was not enough as there are too many characters to replace.
I did find a potential solution using regular expressions & R in the post: http://radacad.com/power-bi-and-regular-expressions, however, I was hoping for an alternative that did not use R.
Pointers / Suggestions appreciated.

Here is one way of doing it. The below code filters rows to only those where Text is equal to just the alphanumeric characters from Text.
This assumes the last step of the query is PreviousStep and the column of interest is named Text.
= Table.SelectRows( PreviousStep, each [Text] = Text.Select([Text],{"a".."z","A".."Z","0".."9"} ) )Regards,
