Change default CSV encoding to UTF-8 for exports
0%
Description
This patch changes the default encoding for CSV exports from :general_csv_encoding to UTF-8.
UTF-8 is now the standard encoding format and is crucial for exporting data with multiple languages or Unicode emojis to prevent character corruption. Therefore, using UTF-8 is the best choice in most cases.
Currently, Redmine defaults to :general_csv_encoding (ISO-8859-1 for English, CP932 for Japanese) for CSV exports, requiring users to manually select UTF-8 each time, which is inconvenient. Switching the default to UTF-8 will simplify this process.
The default was originally set to :general_csv_encoding for compatibility with older versions of Excel, which didn’t support UTF-8. However, modern Excel versions can read UTF-8 encoded CSV files with a BOM. Since Redmine’s UTF-8 exports include a BOM (see #7037), changing the default to UTF-8 will not affect Excel compatibility.
