I do this to get that exact string:

Code:
STRING=$(echo " 2E 2F 4A 6F 73 C3 A9 20 47 6F 6E 7A C3 A1 6C 65 7A 20 2D 20 49 6E 20 4F 75 72 20 4E 61 74 75 72 65 2F 30 36 20 41 62 72 61 6D 2E 66 6C 61 63 0A" |
        sed 's/ /\\\\x/g' | xargs echo -e)

echo "${STRING//[^a-z]/}"

It ought to substitute, I don't know why yours doesn't. Perhaps a bug, or an older shell with limited features.
