ISO-8859-1 seems to lack a horizontal tab, so Sujit's message used a space
character followed by NBSP character instead. It renders fine here
(alpine).
If I reply to Sujit's message using alpine, it retains the original
encoding, and composes the reply in ISO-8859-1 (so it is lossless).
For your reply to Sujit's message the NBSP was converted to the utf-8
sequence U+EFBFBD, because your reply converted back to the utf-8
encoding.
However, U+EFBFBD is not meaningful, so alpine converts it to ???.

Now, when I reply to your reply (this message itself), again, alpine
retains the original encoding (utf-8 in this case) and thus the "…"
character you used is quoted losslessly.
The moral of the story? Beats me. But I'll keep using Alpine.
