I loaded the file using RichEdit1. Reading the file shouldn't be a problem. Rather, the problem is more likely when you try to store the data in a rich-edit control. Those controls don't accept arbitrary binary data.
You need to ensure you only put text in that control. Then remove the invalid characters. Ordinarily, we might use StringReplace to remove characters:. However, it's not binary-safe; it stops at null characters. Instead, you'll need a different function for removing those characters. I've demonstrated that before. Call that function to adjust the string:.

Characters: 0. Invisible Character You might want to copy and paste blank space? What is an Invisible Character? Characters that appear as empty spaces, or invisible characters, are actually Unicode characters They are normally used to represent a blank space without using the space key.
No Installation There is no need to download and install any software to generate empty letters. Copy-Paste Empty Text This feature helps you to send or show empty characters whereever your browser does not allow. Testing Option Once you copy the text to the clipboard, this option allows you to test the generated empty space.
Free to Use The tool is completely free to use for all online purposes. Invisible Characters - Where to Use? You can use the invisible font for several purposes including: Invisible Characters for Fortnite The invisible symbol can be used in Fortnite RPG to hide usernames. Invisible Letters for Instagram, Twitter, and Pubg The empty spaces can also be used on different social media platforms.
It gives a basic overview and nothing more. The problem seems to originate from the FB mobile app on the iPhone and does seem to be related to dictation. FB, if it wanted to, could strip the offending characters and solve the problem — a problem that crops up in no other software that I use where I use dictation — but they are lazy asses when it comes to stuff like this.

NET I'm not willing to make the same assumption for say mono running Linux. Regarding the first solution. Shouldn't a StringBuilder be more efficient than the string assignments? This isn't going to change in the forseeable future, so all you're really doing is doubling the amount of time this function takes to run because you're worried that the definition of a valid path will change sometime soon.
Which it won't. Charleh this discussion is so unnecessary A filename is a part of the path, too. You are not taking correctness over "premature" optimisation. You are simply using bad code.

I think replacing illegal characters with some legal one is more commonly done.
I tested five methods from this question timed loop of , and this method is the fastest one. To address BH 's comment, one can simply use string. Concat name. Add a comment. I use Linq to clean up filenames. You can easily extend this to check for valid paths as well.
ToString , string. Michael Minton Michael Minton 4, 2 2 gold badges 17 17 silver badges 31 31 bronze badges. This did not work for me. The method is not returning the clean string.
It is returning the passed filename as it is. What Karan said, this does not work, the original string comes back. GetInvalidPathChars ; return new string originalString. Contains s. Performance probably isn't great but that probably doesn't matter. Karan or Jon What input are you sending this function? See my edit for verification of this method.
It's easy - guys were passing strings with valid chars. Upvoted for cool Aggregate solution. Show 2 more comments. Contains x. ToArray ;.

I like this way : you keep only the allowed chars in the string which is nothing else than a char array. I know that this is an old question, but this is an awesome answer. However, I wanted to add that in c you cannot cast from char[] to string either implicitly or explicitly crazy, I know so you'll need to drop it into a string constructor.
I haven't confirmed this, but I expect Path. GetInvalidPathChars seems to be a subset of Path. GetInvalidFileNameChars , not the other way round. GetInvalidPathChars will not return '? This is a good answer. ToArray ; — goamn. Join "", fileName. Join "", path. GetInvalidPathChars ; Note that if you intend to use this as a security feature, a more robust approach would be to expand all paths and then verify that the user supplied path is indeed a child of a directory the user should have access to.
Lily Finley Lily Finley 2, 1 1 gold badge 14 14 silver badges 9 9 bronze badges. GetInvalidFileNameChars : The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names.
Then what is the point of Path. I would expect it to return exactly the invalid characters for the current system, relying on. NET to know which filesystem I'm running on and presenting me the fitting invalid chars. If this is not the case and it just returns hardcoded characters, which are not reliable in the first place, this method should be removed since it has zero value. I know this is a old comment but, Jan you could want to write on another filesystem, maybe this is why there is a warning.
If this is too much maintenance effort which is most likely case , this whole method is still a bad idea, because it gives you the wrong impression of safety. Jan I totally agree with you, I was just arguing about the warning. Interestingly this is a sort of "blacklisting" invalid chars. Would it not be better to "whitelist" only the known valid chars here?!
Reminds me of the stupid "virusscanner" idea instead of whitelisting allowed apps Koopakiller 2, 3 3 gold badges 30 30 silver badges 45 45 bronze badges. IMHO this solution is much better than others Instead of searching for all invalid chars just define which are valid.
My choice is the latter, but my answer should at least show you how to do things the right AND wrong way: StackOverflow question showing how to check if a given string is a valid file name.
Community Bot 1 1 1 silver badge. I especially agree with the second advice. I would normally agree with the second, but I have a program which generates a filename and which may contain illegal characters in some situations.
