到 SQL 服务器（和 Sybase 12.5）的 DBI 连接没有 return 希腊字符

Question

我尝试使用 DBI 包连接到 Sybase 数据库，但查询 return 希腊字符不正确。

与 SQL 服务器的连接相同。下面是一个 dbConnect 命令的例子：

library(odbc)
con <- dbConnect(odbc::odbc(), .connection_string = "Driver={SQL Server};server=ATLAS;database=master;trusted_connection=true")

我在使用 RODBC（具有相同的系统 DSN）时没有遇到任何问题

请尝试在 dbConnect() 中设置 encoding 参数。来自 ?odbc::dbConnect

encoding: The text encoding used on the Database. If the database is the same as your local encoding set to ‘""’. See ‘iconvlist()’ for a complete list of available encodings on your system. Note strings are always returned ‘UTF-8’ encoded.
