Commented Issue: chinese text labels sometimes casue crash [24278]

I use both mapwindows4.8.6 and mapwingis4.8 to label the china city names. When the number of the city name is small, it seems work fine. But when I have to deel with many city names, always it will crash after the program run a few time(like just zoomin and zoomout quickly for a few time).

In this page, gischai's last modify seems try to fix the problem I have now, but the edition he fixed is not mentioned, so I have no idea how to fix it in the mapwingis4.8.

_(2)、MapWindow\Data\Vectors\internal\Shapefiles\AttribuTable.cs
修改了ReadTableHeader(BinaryReader reader)函数
将以下3行:
read the field name
char[] buffer = new char[11];
buffer = reader.ReadChars(11);
string name = new string(buffer);
修改为:
byte[] buffer = new byte[11];
buffer = reader.ReadBytes(11);//如果不这样做,就会在后面的读取中,造成读取移位,出错。
string name = System.Text.Encoding.Default.GetString(buffer);
//这样就可以正确读取dbf文件中各字段的中文信息了。_

At last, I attached the shp file, wish it can help to find the bug.
