[gentoo-user] ftp login with ASCII characters?

[gentoo-user] ftp login with ASCII characters?

I am getting perplexed why WYSINWYG:

I was trying to login to an ftp server from the CLI.  Typing in the passwd 
failed every time.  I then set it up as a network connection in Konqueror and 
I had no problem at all connecting using the same passwd.  However, I noticed 
that some additional characters had been added by konqueror's interpretation 
of what the passwd ought to look like; e.g.

Original passwd:  XXXXXXX%02XXXX
Konqueror passwd: XXXXXXX%2502XXXX

Konqueror added 25 to it, after the percentage sign.  True enough when I tried 
the augmented string as a passwd on the command line I was able to login 
fine.  My terminal is TERM=rxvt and shell is SHELL=/bin/bash.  Is there a way 
to simplify this confusion and allow what I type to login normally?  
Otherwise, where can I find what characters I should be typing in for all 
sort of symbols like "^&*[]<>#@" ?

H'lo Mick,

It looks like your problem is the percent sign.  I suggest that you
don't use the percent sign in your password.  FWIW, most other special
characters should be fine.

In URL's, the percent sign is used as an escape character to indicate
the next 2 characters are hexadecimal digits representing a single
ascii character.  As you likely know, letter 'A' is a byte with value
65 (decimal) and 41 (hexadecimal).  In C (and other languages) it can
be represented as 0x41.  Using the percent sign escape notation, 'A'
and "%41" are the same.  Your password contains "%02" which is being
interpreted as 0x02, i.e. as the character whose internal value is 2,
i.e. as CTL-B.

An ASCII chart will give you the decimal and hexadecimal equivalents of
the special characters about which you asked.

HTH,

David

Thanks!  Yes, that makes perfect sense.
