Umlauts in file names
Hi, I am using the v2 API for http. What I found is that if a file or folder name contains a special character, like a German Umlaut like ä, I get a 400 error on upload and download. Is this a bug? ...
I got a solution from Dropbox support that works. You need to escape all non-ASCII characters 'JSON' style. Which means all characters with character codes > 0x7F have to be replaced by a 4-digit hex code (it's hex unicode), preceeded by '\u'. For example Ä would be replaced with \u00c4 in the file name string.
Replacing parts of a string is very straightforward in Javascript, but a little more involved in a language like C.

Dropbox Community ModeratorFor example, in C#, using Json.NET/JsonTextWriter, that would look like:
var sb = new StringBuilder();
var textWriter = new JsonTextWriter(new StringWriter(sb));
textWriter.StringEscapeHandling = StringEscapeHandling.EscapeNonAscii;
// Write things to text writer
textWriter.WriteStartArray();
textWriter.WriteValue("Hello");
...
var result = sb.toString().Replace("\x7f", "\\u007f");
Or, using Json.NET/JsonConvert:
var serializerSettings = new JsonSerializerSettings();
serializerSettings.StringEscapeHandling = StringEscapeHandling.EscapeNonAscii;
var result = JsonConvert.SerializeObject(..., serializerSettings);
result = result.Replace("\x7f", "\\u007f");
- Thank you Klaus!
Upgrading vom Json.net 4.5 to 10 and using the StringEscapeHandling.EscapeNonAscii solves my problem ;-)
Best regards, Horst My file path is saved in a c++ std::string. Can you please provide code to do that character skipping in C++? Thanks.
