Ohh, is it. Might be some settings needed to be tweaked for using
gmail for community patches.

Sure Zorro, I will check it again at my end. However, when I tried using
b4 am -o - cover.1648730443.git.ritesh.list@...il.com | git am

It worked fine for me and applied all 4 patches to my local tree.

I also didn't notice any of such characters in my other inbox
("riteshh@...ibm.com"), which was cc'd too. hmm, strange.

Sure, I will check it once again at my end and resend this.
