Am I right? That appears to be the case. The man page for pbpaste/pbcopy explicitly refers to ASCII. perl -e 'print `pbpaste`' Tends to print ?s for unicode characters or nothing at all depending on the shell. Putting unicode on the clipboard and doing 'pbpaste|pbcopy' consistently mangles the contents of the clipboard in bash, tcsh, and zsh. Looks like a good candidate to file a bug against. Steven
Re: get contents from clipboard
It used to be, back in the days of Apple Classic, that the clipboard contained several copies of the stuff that was placed there. Each copy was identified by one of those four character type codes that are now deprecated in OS neXt. pbpaste, as a tool, does not allow tor an argument for selecting which information type is to be selected. Does it take the first type encountered? Does it default to TEXT, meaning the UTF-8 copy will be ignored? Does it read the UTF-8 version as though it were simple text? Are the type codes no longer supported in OS neXt? And, for that matter, what is the difference between the pasteboard and the clipboard anyway? Some NeXT documentation refers to the pasteboard as equivalent to the current selection, copied or not. -- -- There are 10 kinds of people: those who understand binary, and those who don't --

The pbpaste command seems to know about three types, ascii, postscript, and rtf, and by default it will try to retrieve the clipboard in that order. The initial attempt to retrieve the clipboard in a format can be adjusted with the -Prefer command line argument, (from what I can see from http://www.vorlesungen.uni-osnabrueck.de/informatik/shellscript/Html/ Man/_Man_NeXT_html/html1/pbcopy.1.html the option has existed since the NextSTEP days. The underlying implementation is undoubtedly built on the NSPasteboard object http://developer.apple.com/documentation/Cocoa/Reference/ ApplicationKit/ObjC_classic/Classes/NSPasteboard.html which has an option to represent the clipboard data as an NSString. Oddly enough, NSStrings can hold Unicode strings. The NSString component representation of the clipboard is probably turned into text to be output from pbpaste via a method like -lossyCString.
Re: get contents from clipboard
late in on this one but you can treat the clipboard as a filehandle if
you pipe to pbpaste and pbcopy :
open (FROM_CLIPBOARD, pbpaste|);
open (TO_CLIPBOARD, |pbcopy);
you can then do as you normally would for moving data to and from fle
handles. See the typically useful-in-a-real-world-situation example
script below below which uses this technique - copy a word to the
clipboard, run the script and it will place a backewards version on the
clipboard to be pasted where ever.
#!/usr/bin/perl -w
use strict;
my($data,$word);
my(@letters);
open (FROM_CLIPBOARD, pbpaste|);
open (TO_CLIPBOARD, |pbcopy);
$data=FROM_CLIPBOARD;
if ($data){ $word=$data ;}
else { $word = forwards; }
@letters=split(//,$word);
print TO_CLIPBOARD reverse(@letters),\n;
close (FROM_CLIPBOARD);
close (TO_CLIPBOARD);

Thanks.

If you just want the text, then either of these will do: print `osascript -e 'the clipboard'` ; #or print `pbpaste` ; JD
