I am Hideaki Hagiwara in Japan.
I often use CSV Import file Loader.
It is very useful function.
I like CSV Import file Loader and I recomend my customer to use it.
So, I have a little proposal to Improve CSV Import file Loader.
I would like to add argument Charset to create FileWriter instance at validateFile() method of MImportTemplate class.
*please refer image.
Because, Japanese people use windows-31j Charset at Excel usually, but windows-31j Charset be Error to Garbled characters(Mojibake in Japanese).
UTF-8 is no problem, but I am not sure, other some charset may be Error of Garbled characters like a windows-31j Charset.
I think that to add argument Charset to create FileWriter instance at validateFile method of MImportTemplate class is no problem for UTF-8 too.
And I think this little improvement useful for not only Japanese people, but also other people.
