向postgis中导入openstreetmap下载的北京的地图shp数据时，导入时，当用utf-8，gbk，gb18030都会报：Unable to convert data value to UTF-8 (iconv reports "Illegal byte sequence"). Current encoding is "GBK". Try "LATIN1" (Western European), or one of the values described at http://www.postgresql.org/docs/current/static/multibyte.html.错误，当我把编码格式改成LATIN1时会成功，可是中文显示的就是中文乱码，请问有比较了解，或者遇到过这个问题的嘛？求解决。
