charset/base64 encoding/encode.

Still futzing around with email and character sets.

Under Encode and perluniintro there's mention of
octet          \x{..} (255 chars up to \xff
string         some internal representation
code point     \x{...} 1, 2 or more bytes of data

But I'm not sure about the order of things.

So I'll try this:

I have a MIME messsage part like the following:

Content-Type: text/plain;
Content-Transfer-Encoding: base64


MIME::Base64 has a function
my $decoded = decode_base64($DATA);
that returns really wonderful crud to my screen.  But I can't regex it.

I think it returns octects.  At least that what MIME::Base64 says.
So I should be able to do

my $base64 = join('',<DATA>);
my $octets = decode_base64($base64);
my $utf8 = decode('Big5',$octets);

and from there I can use something like /(\w+)/ on it.
(But IIRC /[\w]+/ will act weird).

printing it out require 'binmode(...)' but I can do stuff internally to the program.

Which is all good.  And I guess it's progress.
But can I expect to ALWAYS find a charset declaration on the Content-Type line 
if it isn't just ascii?  (There is sometimes a content-type in the header which 
I assume applies to all)

[Encode] Encoding vs. Charset
Encode hackers (Especially Autrijius) I am now fairly content with the feature set of Encode so I decided to write some programs based upon it. And I have found that most of Chinese (Continental; seems like Taiwanese are much more technically correct) and Korean mails and web pages confuse "charset" and "encodings". That is, charset="gb2312" really means euc-cn and charset="ks_c_5601-1987" really menas euc-kr. Sadly this misconception is enbedded to popular browsers. So when you try something like my ($encname) = /^Content...

Encode vs encoding
Hi to all list users. Can someone *please* explain me the difference between (except the scope) encoding and Encode::encode()? I know encoding affects all the code, but what else does it do to do the right thing or am I missing something with Encode? I'm using ActivePerl 5.8.4 build 810 under Windows 2000 and here are the examples: #!/usr/bin/perl -w use strict; my $char = "\xFE"; print ord $char; # prints 254 #!/usr/bin/perl -w use strict; use Encode; my $char = "\xFE"; $char = encode 'ISO-8859-9', $char; print ord $char; # prints 6...

Charset encoding
Win7HPx64. TB13.0.1 In Tools | Options | Display | Formatting | Fonts | Advanced | Character encodings I have the default encoding for both Incoming and Outgoing Mail set to Western (ISO-8859-1), and, where possible, to use the default encoding in replies. Why, then, replying to a newsgroup posting in UTF-8, did my post also appear in UTF-8?

Html.Encode encodes too much
Hi, When I output some french characters like é è ç à with Hml.Encode, they are escaped as &#233; &#232; &#231; &#224 in the generated HTML. I fear to see almost everything escaped if I translate my application into korean or russian. If I am not wrong, only < > & and " should be escaped. All the other characters are handled directly by the HTTP response encoding (iso-8859-1 for my french characters) and thus should be kept as is in the generated HTML.   Is there a way to override the default Html.Encode by another one ?   It's p...

Encode::encode MIME-Header
The routine should not gobble up white space. This leads to all manner of bad side-effects, such as encoded words starting and ending with spaces where you'd want words surrounded by spaces, or encoding sequences of words instead of single words.

Hi,I have created a generic handler that outputs resized images.

Base64 encoding
Hi all! My question is as follow: How can I convert binary data (blob) into a string encoding Base64 and viceversa? I need it without using the Windows API functions CryptBinaryToString and CryptStringToBinary wich fails in W2000 (only works OK in XP and W2003). Is there any algorithm implemented in PowerBuilder that performs these features? I know that in VisualBasic they exists. Thank you in avance for your help Regards Fran I hve just find out the response in PFC forum: Search for a PBNI PowerPack on CodeXchange
