Windows R R dotnet AccessViolationException

问题描述

场景如下：我使用 R dotnet 的程序将在以下情况下崩溃：

它由以“系统”用户身份运行的计划任务调用
它由以我的“管理员”用户身份运行的启动任务调用

只有在我的 csv 文件中包含名为“ClientName”的特定列时，它才会崩溃。列值只是字母数字值。

当它崩溃时，它看起来像这样：

Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException
   at RDotNet.Expression.TryEvaluate(RDotNet.REnvironment,RDotNet.SymbolicExpression ByRef)
   at RDotNet.REngine.Parse(System.String,System.Text.StringBuilder,RDotNet.REnvironment)
   at RDotNet.REngine+<Defer>d__63.MoveNext()

   at RDotNet.REngine.Evaluate(System.String,RDotNet.REnvironment)

失败的命令最终看起来像这样（发送到 REngine.Evaluate 的命令）：

你可以看到它在崩溃时被切断。

正如我所说，如果我在登录时手动运行 exe，则不会出错。只有当我有一个计划任务作为“系统”用户运行它时，我才能重现它。如果我删除“ClientName”列，它也不会崩溃。

任何有关下一步尝试的建议将不胜感激。我尝试了许多版本的 R，但目前使用的是最新的 4.0.4（我也尝试过 3.6 和 3.5）并使用 R dotnet 1.9 版。

*编辑好吧，我找到了罪魁祸首。我的“ClientName”列中有一个包含 unicode 字符 8211 的值（EN-Dash）。我仍然不清楚为什么这只是一个问题，如果作为系统用户从计划任务运行。现在我可以强制使用 ascii 字符来解决我的问题，但在某些时候我可能需要包含 unicode 字符，所以我猜这会再次困扰我。
