Commodore 64 PETSCII Codes
Here is the second most frequent table that I find myself using, after screen codes: The PETSCII table.
UPDATE: December 10, 2021
Originally these were laid out in horizontal rows as Block 1, 3, 5, 7, and then on the next row, Block 2, 4, 6, 8. I did it this way because I copied the layout found in the Complete Commodore Innerspace Anthology. However, upon working with PETSCII for a few years, I've realized that it makes a lot more sense to show the low 4 blocks together, and the upper 4 blocks together.
It believe this new layout makes it easier to see the relationship between the upper and lower blocks. Merry Christmas!

UPDATE: January 22, 2018
The "Discussion" section below, replaces the original "notes" section.
Discussion
I have updated this PETSCII table to agree with the Vic-20/C64 SuperChart. So, please read the end discussion of that post for a more complete understanding of why the chart above appears as it does, and why it differs from the original source: http://sta.c64.org/cbm64pet.html.
The table above has been sub–divided into 8 blocks. This makes it easy to reference, because PETSCII is fundamentally divided into functional blocks of 32 characters each.
Blocks 1 and 5 ($00–$1F, $80-9F) are control codes. Printing them will cause a change in the screen layout or behavior, but no actually character will be displayed.
Blocks 4 and 8 ($60-$7F, $E0-$FF) are not used. If they are printed, the KERNAL will interpret them as mirrors of blocks 7 and 6 ($C0-$DF, $A0-BF) respectively.
UPDATE: April 16, 2018
I found this PDF description and overview of PETSCII on aivosto.com. I thought it might be of interest to anyone interested in PETSCII in more detail. I haven't looked over the document thoroughly, and I'm not responsible for any errors it may contain.
