库需要utf-8。我尝试使用以下方式将us-ascii文件转换为utf-8：
iconv -f us-ascii -t utf-8 src.csv > target.csv
当我这样做的时候：
file -I target.csv
它仍然显示字符集为us-ascii。然后我发现us-ascii是utf-8的子集，该文件只能猜测文件类型。
但是，如果我使用src.csv作为TextLMDataBunch.from_csv（）库的输入，它就可以工作。如果我这样做：
cat src.csv > target.csv
然后将target.csv用作同一库的输入，它不起作用并出现以下错误：

有人可以告诉我怎么了吗？我正在Google Colab上尝试此操作，并在Colab和Mac上尝试了字符编码更改，但没有结果。
