In Retail Express although you can add illegal characters in the web interface, these characters will generate errors when doing any Mass uploading or downloading. We can sometimes load the data without the web description or long description which is the likely cause. If you copy text from a web page you can get illegal invisible characters including ZERO null characters many are invisible to see. 

So For SKU’s you can only use the following:*

a-zA-Z0-9/+-._

*SKUs cannot contain a forward slash "/" in Neto


Any other characters should not be used.


For Description's commas “,” and back slashes “\” are not permitted


There was a release late in 2019 where the characters and symbols that can be used with retail express was adjusted, some reports were having errors do the to characters. Please find the link below of the new valid ones.
