Problem with QA check-Regular expressions-Wrong degree symbol

Question

I have created a Regex Expression QA check with the aim of detecting whether I am using an incorrect degree symbol in my projects. 
 
 The idea is simple. If I find a digit followed by an ordinal symbol "&ordm;" (note, ALT+167 "&ordm;" which is wrong as a degree symbol, NOT &deg; (ALT+248) which is correct), it should show a mistake. 
 
 Like this: 
 
 Well, it does NOT work. \d matches any digit, and &ordm; should match, well, "&ordm;"... but it does NOT work. I have even changed it for its ASCII entry, \d \xBA , and it DOES NOT work either. Neither does its Unicode code, \d \u00BA . And I have run out of options... 
 
 Any ideas? can someone replicate this and see whether I am making a stupid mistake or Trados has just the strangest error with something as simple as an ordinal symbol? 
 
 For your reference, I checked either solution in RegexBuddy and they find my string perfectly!!!

Hi Ignacio Niveiro 
 I have tried to replicate your QA check and it works. Did you add the QA item with Action/Add item? Regards Stefano

Hi Ignacio Niveiro , 
 
The regex also works for me. Are you sure you have the characters in your text that you have referred to, and are you sure you used the correct action? I used target check only and I used your expression.
