If I m not wrong you have that character at table so you can get char from the record value with position and use char value for ax str functions (strRep,Rem etc.)

Or you can search ascii value of the char at internet and use it in the code

Select the record and set to a string valuable. Get lenght with strlen. Loop it and get every value with char2num. You can get ascii with this. Seach İnternet with this value and do whatever you want at next step

Your screenshot shows two characters. Are you saying that you want a solution for these two characters only? I doubt so. Also, there may be some special characters that aren't actually displayed.

I believe you need something more generic, but you haven't yet thought about your requirements. You must think about what you actually want before you can write code doing such a thing.

You mentioned ASCII, therefore you may want to remove all characters that aren't in the ASCII table, but it's not clear whether it's safe enough. There may be non-ASCII characters that may be acceptable. Also, ASCII contains characters that aren't valid for an invoice number, such as the vertical tab. Therefore accepting all ASCII table isn't really safe, although it may be acceptable in your code. Maybe you rather want to accept selected Unicode character categories, or something like that.

Well, that you have the problem with these particular characters today doesn't mean that you won't run to another character tomorrow. Even the title of this thread asks "how to replace or remove any invalid characters".

But anyway, you can use strReplace() to find and replace a character in a string. If you want to remove it, replace it with an empty string.
