Dear monks teach me something.. I'm having this issue a lot lately. I either scrape a website, or a pull in data from a csv, and I get stupid garbled non-sense like this:

SERIAL#          �-----------------. WD2PD644366123

[download]

I know what to do insomuch as this involves using `od` but when it comes to ridding the characters in perl, I always get lost, and up figuring it out with an almost brute force approach.

So `od -c` will output

0104200       D   5   3   0   0   6  \n   S   T   O   C   K       N   
+O
0104220 375   -   -   -   -   -   -   -   -   .   .   .   .   .   .   
+.

so the character I want remove has a od code of 0375 -- obviously that isn't right..

`od -xc` will return this 

 2dfd 
 375

[download]

not sure what this means

`hexdump -c` returns 

0008880       D   5
0008890 375   -   -

[download]

so 375 is obviously significant in `od -c` (oct) or `hexdump -c` (hex) ... Could someone please explain or point me to where I can find out how to use these utilities effectively, and how I strip them from text, I thought a simple tr/\{something here}//d would work...

Problem found

See Re^2: hexdump/od/perl question which is on this thread. Note to readers you don't always address octals with a leading 0
