I'm using Sharepoint 2013 and having a problem and I found some records in UserData table that seem to have Chinese characters in the column. The column where I see this is the tp_ColumnSet. This column is XML of the values in the list that it belongs to. I have found this list in SharePoint by using the tp_ListId and looking up in AllLists the list that matches that ID.
Here is the XML for this record.
<float1>1.200000000000000e+001</float1> <float2>2.000000000000000e+002</float2> <float3>3.000000000000000e+002</float3> <float4>4.000000000000000e+002</float4> <int1>497</int1> <int2>2</int2> <int3>497</int3> <int5>31</int5> <ntext2><div class="ExternalClass9DB19E6929B74D6EB9D92825BBE42503"><p>ESTA ES UNA PRUEBA<br></p></div></ntext2> <nvarchar1>TICKET DE PRUEBA</nvarchar1> <nvarchar3>(3) Baja</nvarchar3> <nvarchar4>Iniciada</nvarchar4> <nvarchar8>醩㹈䒂伷垎짞蜑</nvarchar8> <nvarchar9>ꭶ♛䭬墶✄弆럒</nvarchar9> <nvarchar10>橉桸䒦嚌ᤙ䀰銫</nvarchar10> <nvarchar11>蘄톾䣡蚀粚智棩</nvarchar11>
Google translate doesn't seem to understand these characters. I picked several different languages but none of it makes much sense. We don't have any Chinese, Korean, or Japanese language packs installed, so I don't know why this content is in there like that. Does anyone know what this says, or why it is in there? Has my SharePoint been compromised?
