我有个sas dataset, 是在中文下生成的（即双字节），现在需要用英文的sas 来读入和处理（即单字节），但是因为字节不同，读入的总不对，这种情况怎么处理，请说的详细些，比如用什么语句，命令，keyword等等。电脑系统是windows 7.谢谢
data a (encoding=wlatin1);
set r.chinese (encoding="euc-cn");
run;
ERROR: Some character data was lost during transcoding in the dataset WORK.A. Either the data contains characters that are not representable in the new encoding or truncation occurred during transcoding.
我的r.chinese dataset里只有英文字母和数字，字节是双字节。
