Thanks for mechanize–we use mechanize at work and it works well.

Question on strings:  
I seem incapable of figuring out how to ‘recreate’ this string in  
“string” format:

Here it is byte by byte

bytes = [100, 101, 110, 116, 226, 60, 56, 48, 62, 60, 57, 57, 62, 115,  
32, 112, 114, 101, 118, 105, 111, 117]  
for b in bytes do all \<\< b; end # create the string  
all == “dent?\<80\>\<99\>s previou” # it compared with itself in string form

?  
Thanks!

In other words:

pack, Pack!

The roster of community members whose last names are core methods  
(give or take a capital letter) is growing. There are at least three  
at this point (Freeze, Keys, and Pack).

Questions:

The following ways all recreate my original string, however I am having  
trouble getting the comparison work to itself expressed in string  
form–it’s like the string form doesn’t express all the inside chars or  
something–am I missing something? Is there a way to recreate the  
string along the lines of “dent?\226” and, as a follow up, is  
complicated\_string.inspect just not displaying the interior characters  
right?

Just wondering if anybody can enlighten me.  
Guess we just need more people named by Ruby names, huh?  
Take care.

The character whose ASCII code is 226 is not a question mark.  
The ASCII code of a question mark is 63.

irb(main):008:0\> puts [100, 101, 110, 116, 226].map{|n| n.chr}.join  
dentà 
irb(main):009:0\> “342”.to\_i(8)

Octal for 226 is 342.
