Force the enclosure character with the CSV writer

[danakil]

The CSV writer use the standard php fputcsv(), which will only wraps the value under the following circumstances:

• one of the CSV control character is present in the field (delimiter, enclosure or escape character);
• the newline or the tab character are present in the field \n, \r, \t
• the space character is present In the real world, this can lead to problem with systems that explicitly require that all fields are wrapped in quotes.

May it be possible to add an option (or create a new writer, or some other method) to force the enclosure character (in other word, to no use fputcsv but some custom code) when required ?

this can lead to problem with systems that explicitly require that all fields are wrapped in quotes

But those systems don’t adhere to the RFC for CSV, which states that only

[f]ields containing line breaks (CRLF), double quotes, and commas should be enclosed in double-quotes.

So while we won’t add this to the core, you can still enclose your values in (say) double quotes by adding a converter.
