The "Encoding" drop-down is supposed to default to the encoding defined by @general_csv_encoding@ in @config/locales/*.yml@ files. For example, it should default to "ISO-8859-1" when the language of your account is English.

However, the drop-down always defaults to "US-ASCII" regardless of @general_csv_encoding@ if the language of the current user is Korean (ko), Thai (th), or Simplified Chinese (zh).

This is because the value of @general_csv_encoding@ in those languages is not found in @Setting::ENCODINGS@ in @app/models/setting.rb@.

|. Language |. general_csv_encoding |_. How to fix |
| Korean | CP949 | Add @CP949@ to @Setting::ENCODINGS@ |
| Thai | Windows-874 | Add @Windows-874@ to @Setting::ENCODINGS@ |
| Simplified Chinese | gb18030 | Change @general_csv_encoding@ in @zh.yml@ from @gb18030@ to @GB18030@ |
