Here's a Perl filter implementation that emulates the old Convert to
ASCII plug-in. Save it as "Convert to ASCII" (or whatever name you
want) in your Unix Filters folder:

~/Library/Application Support/BBEdit/Unix Support/Unix Filters/

The old Convert to ASCII plug-in dialog allowed you to configure the
output for: 'ß', '«»', and '•'. I've commented out alternate
substitutions for this characters.

Hope this helps,

-J.G.

Thanks a bunch for your perl filter, but can anyone help me with the
behavior I get when I run it? A couple examples:

‰ -> ,Ae()()
© -> -(c)
¥ -> -*

When I run it from the command line, I get the same conversions. If it
makes any difference, I have perl v5.8.1-RC3 (I've never installed this,
so I have whatever has been brought up with OS X).

Thanks!
Tim

BB folks, please don't take John's script as a reason not to put that
feature back in... He did a great job, but there's nothing like the real
deal.

We most likely will return Convert to ASCII to the lineup; usual
disclaimers apply. :)

These work here. (I tested the script against the output of the
Convert to ASCII plug-in in Mailsmith.)

Perhaps this is a text encoding problem. I have the filter saved as
UTF-8/no BOM; and in the Unix Scripting prefs panel, I have "Use
UTF-8 for Unix Script I/O" turned on.

Since you're in a contrite mood (well, I can imagine it at least)
please also rethink that saved-state-disappears-after-14-days thing
people have mentioned here. Until that's fixed (put into a Pref I
suppose) I'm up close and personal with 7.1.4. I _like_ where I put my
windows, even if I last opened them 6 months ago.

And while I have your ear, thanks for the drawer - I can see myself
getting to like that, soon, I hope.

Well, since it's impossible for you to have been using the software for
either 14 days -or- six months at this point :-), may I recommend that
you give it a try first?

Thank you, thank you, thank you! I'm having a little problem with the script, though, which I think has to do with the fact the BBEdit is treating the text I paste in as Unicode instead of ASCII.

I copied the following test from a web site:

d—it

that second byte should be an en- or em- dash. When I hex dump that window in BBEdit, I see:

0000: 00 64 20 14 00 69 00 74 ¿d ¿¿i¿t

Two bytes per character? Not ASCII. When I run your script, I get:

d,Aeiit

If I copy the same text to a window in Mailsmith and run "Convert to ASCII", I get:

d--it.

So I guess the question is, how do I get BBEdit to treat the text I paste in as ASCII instead of Unicode. Thanks!

Ken

You're confused about what ASCII is. ASCII is a 7-bit text
encoding format -- it only contains normal characters like a-z and
A-Z, and standard U.S. punctuation characters.

Any text document containing other characters is in some sort of
non-ASCII text encoding format. On the Mac, this is traditionally
Mac Roman. On Windows, it's often Windows Latin 1. Unicode encodings
such as UTF-8 and UTF-16 are richer (thousands of characters,
instead of only 256), cross-platform, and more fragrant.

I think your problem with this text filter is similar to the one
reported yesterday. I suggested:

> Perhaps this is a text encoding problem. I have the filter saved as
> UTF-8/no BOM; and in the Unix Scripting prefs panel, I have "Use
> UTF-8 for Unix Script I/O" turned on.

In other words, open the "Convert to ASCII" filter file in BBEdit,
make sure it's saved as UTF-8/no BOM, and then turn on the
aforementioned preference checkbox.

See if that works for you.

Regards,

-J.G.

No, I'm pretty sure I know what ASCII is, having written an EBCDIC to ASCII translator for an IBM S/36 a number of years ago. :-) Not to pick nits, but this statement is not quite true. The first 32 characters in the ASCII character set are non-printing control characters.

It did indeed. Thanks!
