That's bad OCR, that's an apostrophe, a Ka, and an E, with the apostrophe
being interpreted as a matra somehow.
I bet there are only a couple of OCR algorithms out there handling Bangla.
Indic scripts aren't something you can OCR glyph by glyph in such a
straightforward way due to ligatures, so these algorithms are probably
noticing components of a character and producing it. It sees a preceding
line and the curve above, and interprets that as an I. It also sees the
proceeding line and curve above, and interprets that as an EE. It then just
puts the two together. It shouldn't, but it does.
Given a small set of OCR algorithms I think it's reasonable to assume that
such aberrations would be common across outputs -- so hundreds of hits for
a typo doesn't sound out of the ordinary to me.

I went through the results for ঘিা (0998 09BF 09BE). Most occurrences are
actually ঘন্টা (0998 09A8 09CD 099F 09BE), "ghanta" which can mean "hour"
or "bell". Reasonably common word. These documents don't look scanned --
the text isn't garbled or anything, but it could be a cleaned up scanned
document because I copied out some more of the text and there were similar
aberrations all over the place. For example, in [1] the letter ব ("ba") is
used frequently, but is written with a fancier script where it has an extra
line through it. Many occurrences of it have been interpreted as sequences
of vowel diacritics. The last line of the second-last stanza on page 5 has
an absolutely ridiculous number of consecutive diacritics in the PDF text.
