Henrik -

No worries. I have no intention of changing our CGIConvMode, but I did
want to make sure I understood the implications. The bulk of our CGI
programs produce text/html and they work perfectly fine.

I plan to tweak the programs that produce JSON output and leave

everything

else alone.

btw if you use binary or recieve application/xxxx content type the input

is recieved as binary without conversion to ebcdic

you are right

It's OK because I know enough to get what he was saying. It makes it
pretty clear in the HTTP Server documentation that if you add
"charset=utf-8"
(really, charset=anything) that no conversion occurs on the body.

I have never tried CGIConvMode %BINARY%, but wouldn't that mean that

all

your content has to be UTF-8, including output with

"content-type:text/*"?

I know English is not your first language, but I couldn't

understand

that

at all :)

But anyway, my observations are not relevant because we always use
"CGIConvMode BINARY"

apache doesn't neither converts from an ebcdic body if you send

then

the

body also has to be pre-encoded in utf-8

Content-Type: text/html; charset=utf-8

Hello Henrick. That's sort of what I suspected. Do I have to

change

the

CGI program to produce ASCII output, or is there a way to tell

Apache

to do an EBCDIC to ASCII conversion on an

"application/javascript"

content type?

We have several CGI programs that generate javascript,

usually

JSON.

For years we have set the content type to text/plain or
text/javascript. I'd like to start using the more standard
"application/json", but I am

hitting

a major snag. The output is garbage. I get the exact same

output

when I set the content-type to application/javascript.

Just to verify this was related to CGI output, I used AddType

to

change

the

content-type of static JavaScript files to

"application/javascript".

Those

files look fine, so this must have something to do with it

being

CGI output.

I don't really know what is up with the output, but I know it
isn't EBCDIC. It doesn't convert. Garbage in, garbage out.
Changing the

content

type back to text/javascript sets everything right.

Anyone have any guesses what is going on here? We use CGIDEV2
under IBM i 7.1. The default CCSID of our CGI jobs is 37.

Just so we are clear on one thing. We had the following

settings

in our HTTP Conf:

DefaultFsCCSID 037
CGIConvMode %%EBCDIC/EBCDIC%%

I commented both settings out and it had no impact on the

output

whatsoever. All of our CGI programs that use content type of

"text/*"

seemed to work. The ones using "application/javascript" or
"application/json" for content type still looked like

garbage.

The only guess I have is that mod_cgi sees that the

content-type

starts with "application" and treats the output as binary,

but

I

have no idea how I

can

tell mod_cgi to treat "application/javascript" as text, or if

that

is

even

the issue.

I am hoping someone has an idea. I know Apache pretty well,

but

this one has me stumped.
