odd characters moving mac files to pc

12.20: mis.addn/mac/odd characters show up moving to pc:

. used editor to fix bad apostrophe's for entire 2009 log *.txt

by replacing [large O with ~ over-head] with "(') .

. looking at the results, it appears that

[large O with ^ over-head] is sometimes paired with

[large O with ~ over-head], as if they're in the habit of using a right-side quote

in place of an apostrophe .

. I never noticed these on the mac, apparently because mac was

graphing them correctly, or translating to something non-std (atleast for pc world) .
