"message": "No mapping for the Unicode character exists in the target multi-byte code page",
"data": null
}

Using ** DMVCFramework Server ** build 3.2.2 (nitrogen)
Delphi 10.4 Update1

The error arraise when trying to read string fields containing portuguese characters Ç

To reproduce just try to process that kind of data using TMVCActiveRecord

The error raise in MVCFramework.Serializer.Commons.pas
line 1132: lSStream := TStringStream.Create('', TEncoding.Unicode);
That line was changed to lSStream := TStringStream.Create('', TEncoding.ASCII);

Update:
In line 1132 remove entirely the encoding:
lSStream := TStringStream.Create('');

That assign the TMBCSEncoding class as the default encoding. More in:
http://docwiki.embarcadero.com/Libraries/Sydney/en/System.SysUtils.TMBCSEncoding
It appear to be a better solution

and the error disappear and now all working normally, but I dont know if that will have some other impact more ahead in others areas of the Framework.
Also if the problem is proved to be a bug, please pull fix in source files.

But situations diferent in it owns ways

The real problem is not of DMVCFramwork, but of Embarcadero itself, as can be read here:

The proposed solution is just a workaraound, but not the optimal one

Thanks.

I did the change. All the Unit Test are OK, but it's a border case. Can you provide a specific test which would arire the problem so that I can add the test in the unittest project?
