Regex: How to remove all non-printable characters - including nulls

I want to remove all non-printable characters - including nulls.

I could extend the following by adding as many printable characters as I can
think of.

But I wonder if there isn't something better.

Like a \something that does it all?

Return Regex.Replace(oStr, "[^\w\.@-]", "").Trim

Then I want to trim the result of white space.



Do you know how to do that?



thanks in advance

No, there is no magic code that includes only printable characters, as
being printable is not a property of the character itself.

What decides if a character is printable or not, is how you are trying
to print it. Different fonts include different characters, so a
character that is printable using one font may be not printable using
another font.
 
How about, replacing all control characters with ""


thanks

Active,

Are you living in China, please tell us, because those printable characters
are not the same as in Indonesia.

The pattern [\x00-\x1f] matches all control characters including the NUL
character.
