将Nvarchar数据类型导出为CSV

Question

I'm attempting to export international characters from query to csv. Output to the browser works fine, as does writing to Excel using CFSPREADSHEET.

I have the following set up:

• The datasource connection uses JDBC
• Table fields are nvarchar

Rendering the file is as follows:

<cfset filepath="c:/test.csv" />
<cfloop query="q">
  <cfset string = "" />
  <cfset string = listAppend(string, q.fieldname) />
  <cffile action="append" file="#filePath#" output="#string#" charset="windows-1252" />
</cfloop>
<cffile action="readbinary" file="#filePath#" variable="bin" charset="windows-1252"> 
<cffile action="delete" file="#filePath#" /> 
<cfheader name="Content-Disposition" value="attachment; filename=Output.csv" charset="windows-1252"> 
<cfcontent type="text/plain" reset="true" variable="#bin#" />

However, certain characters are not converting properly. For example:

• Jørgen shows as Jørgen
• Sälzler shows as Sälzler

Update - Adding charset="windows-1252" did solve a majority of the bad conversions including the above examples. The following still do not convert

• Krčobić shows Kr?obi?
• Mirosław shows Miro?aw
• Bożek shows Bo?ek

Supposedly Excel has issues with UTF8 CSV files. One suggestion is to append a BOM to help it along, but results are mixed for different versions. See the full thread for details.

... build file string ....
<cfset FileWrite(filePath, binaryDecode("EFBBBF", "hex"))>
<cfset FileAppend(filePath, string, "utf-8")>

<cfheader name="Content-Disposition" value="attachment; filename=Output.csv" charset="utf-8"> 
<cfcontent type="text/plain" reset="true" file="#filePath#" deleteFile="false" />
