Umlauts in IDL 6.0 and 7.0

#1 08-20-2008, 08:20 AM

Dear all.

I have encountered an annoying problem with IDL 7.0 (German version,
German keyboard). All the umlauts within programs I wrote with IDL
6.0 are changed to some weird characters. Also, when I use

Xyouts, 0.5, 0.5, 'ä', Align = 0.5, CharSize = 4, /Normal

IDL 7.0 displays two special characters, while IDL 6.0 correctly
displays "ä".

When I enter

print, byte('ä')

in IDL 7.0's command line I get "195 164" as a result.
IDL 6.0 correctly prints "228".

Also the degree symbol is incorrectly displayed.

So what is going on here? Do I have to change the character set or
something? How do I do this?

Might be a solution (assuming you are familiar with LaTeX).

I realise this does not address the root of your problem. I haven't
taken the plunge to IDL 7 yet.

It looks to me that IDL70 is giving you two numbers equivalent to
hexnumber c3a4 which is exactly the hexcode for 'ä' in UTF-8. I guess
it can be solved if there is a way to force IDL to think in UTF-16 or
UTF-32.I'm not sure how to solve it but here's a "virtual kwyboard"
for you(http://tinyurl.com/fontart).

Hey, that's a cool app! When I saw the start of this thread, it got me
thinking how useful such a thing could be, and when I got to the end,
I saw someone had already written it!

That said, it would be much more useful to me in sourcecode form, so
that I could run it to generate code sequences within a development
instance.

The wiki says "source code available upon request," but there are no
email addresses...

Cheers,

Ok, I understand the problem now, but, I could not find a way to solve
it...
Is there really no one else who has the same trouble? Any users from
Germany?

Many thanks for this link! That really is one nice program!

Thanks,
