R – writing out a null in javascript

asp-classicjscript

This question is in follow up to this one: write binary data using JavaScript on the server.

The problem there with just using Response.Write to write the string is that the string contains a null character which JavaScript recognizes as the end of the string.

The string I'm trying to write starts with the following (written here in character codes)

255 216 255 212 0 16 ...

JavaScript will only output the first 4 characters here, because it recognizes the 5th as a string terminator. Is there any way around this?

I should note that I really do have to write out the binary null… the output of this is pdf, so I can't change the output format.

What about base-64 encoding the data? You'll need to decode it of course.

Why not simply use:-

Response.Write(this.buffer)

Assuming the codepage of the response is set correctly (I.e., its the same as in the Locale that the VBScript is running in) then Response.Write should do the same conversion that your StringToMultiByte is doing.

I suspect you've tried this and is hasn't worked. If so I really think you need to look into why that is rather attempt this strange usage of BinaryWrite. Currently your solution is going to kill your server.

Mysql – ASP, MySQL and UTF-8

You need to specify the character set in the connection string using the charset parameter; see the MySQL ODBC doco. e.g. add ~~"charset=utf8;"~~ "charset=ucs2;" to your connection string.

Edited: I finally got a chance to run a simple test harness on this, and it does indeed fail with charset=utf8. However, since VBScript is running internally with UCS2, I gave it a try with charset=ucs2 and it works fine. NB: page is still set to send all output as UTF-8, it's just that VBScript is pulling data from an ODBC connection using UCS2. Job is done :)
