Can't remove invisible characters

Hi everyone,

I received those data from SQL server. They look normal in SQL but when importing to Power BI, some of them contain invisible characters that I can't remove them. I have tried to trim, substitute, remove white space but they couldn't help. 

My wish is to extract only number from those strings.

I appreciate very much if you can solve this problem.

Thank you very much!

Regards,

Cindy
