in the output is not quoted. When used in a reader, the quote characters are included in the field values (normally, they are processed as delimiters and stripped).DialectA comma-separated value file does not have a well-defined standard, so the parser must be flexible. This flexibility means that a number of parameters can be used to control how the CSV parses or writes data. Instead of passing individual parameters into the reader and writer, you c
1. Problem Description
We deployed a mantisbt bug submission system. After the language is set to Chinese in config_inc.php, the interface is changed to a Chinese interface. However, in the problem column, we export the CSV file and we will find it garbled, the exported Excel file is suffixed with XML. Although it can be opened through the Excel software, the wor
