Hello,

I test Cinder-Protocol with [HttpServerApp](https://github.com/BanTheRewind/Cinder-Protocol/tree/master/samples/HttpServer) and UTF8 character like é à…

I send with firefox :  
\>

> ```
> <div class="form-group">
> <label for="text_0">Text Box 0</label>
> <textarea name="text_0" class="form-control" rows="3"></textarea>
> </div>
> <div class="form-group">
> <label for="text_1">Text Box 1</label>
> <textarea name="text_1" class="form-control" rows="3"></textarea>
> </div>
> <div class="checkbox">
> <label>
> <input type="checkbox" name="checkbox">A Check Box</input>
> </label>
> </div>
> <button type="submit" class="btn btn-default">Submit</button>
> </form>
> 
> ```

After it display into firefox :

> ```
> "text_0=éé
> text_1=àà
> checkbox=on
> "
> 
> ```

I receive in C++ console :

> ```
> POST / HTTP/1.1
> Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
> Accept-Encoding:gzip, deflate
> Accept-Language:fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3
> Connection:keep-alive

> 
> ```

> ```
> text_0=éé
> text_1=Ã Ã
> checkbox=on
> 
> ```

I don’t understand why text\_0 and text\_1 is not well formated éé and à Ã

Any idea ?

Thanks

Try adding the correct charset, see:

It was already added in httpServer code response C++ like :  
mHttpResponse.setHeader( “Content-Type”, “text/html; charset=utf-8” );

and into html file like :  
meta http-equiv=“Content-Type” content="text/html;charset=utf-8"  
meta charset=“utf-8”

Could be that the output console only supports ASCII. I know that’s the case in Visual Studio.

Any updates on this matter? Dis you sorted out colin?

I’m now coding in portuguese OS’s and will do some webservices request ans listeneners, so would aprecciate to render them in a TextBox.

**EDIT** : For future use of myself and other in non english OS’s this can remove runtime error, turnig all received/used string to UTF8:  
\> std::string temp;  
\> utf8::replace\_invalid(originalString.begin(), originalString.end(), back\_inserter(temp));

With #include “utf8cpp/checked.h”
