RegEx replace multiple characters

[Jean-Yves_Pochez]

The web shows these kinds of examples:

var article = a.replace(/ |\./g, "_").replace(/\r?\n|\r|\$|\#|\[|\]/g, "")

But I don’t know if Xojo RegEx can handle this, appears not to be standard.

this is multiple replace of one set of characters by one other.
you do multiple regex, one for esch set of characters.

Before using a FolderItem.name (s as string) in a RegEx:

s=s.ConvertEncoding(Encodings.MacRoman)

What I found in Xojo: the Encoding of a text (• test ü ä 123) typed and copied from the finder are both UTF-8. But the length/length(bytes) is different: 14/18 vs 16/20. Does this information lead somehow to a solution?

I was not saying that at all…

Use Xojo / a FolderItem to get the file name whose file holds a ü (…) in it and apply that DisplayName to a variable.
Add a break,
Look at the variable contents AS HEX: you will see a three Bytes value that defines that ü.

And, yes, there is a solution. I get one, with details (somewhere in this Forum). I understand the demonstration (the file name as read by Xojo from macOS is UTF…), but I never understand how to deal with it / convert the Encoding to UTF-8. Sorry.
