Is there a way to remove every other character in a paragraph?

If you're in a hurry, and don't want to purchase a program to take care of the issue, perhaps you could:

(1) Use your word processor's Find & Replace:

aa with a

bb with b

cc with c

dd with d

ee with e

ff with f

gg with g

hh with h

ii with i

jj with j

kk with k

ll with l

mm with m

nn with n

oo with o

pp with p

qq with q

rr with r

ss with s

tt with t

uu with u

vv with v

ww with w

xx with x

yy with y

zz with z

If you're using a decent word processor, you can make the Find & Replace feature ignore the difference between uppercase and lowercase letters. Otherwise, you'll need to do the same thing above, but with uppercase letters.

Going through the preceding steps will greatly reduce the number of double letters.

Of course, dd, ee, mm, nn, pp, rr, ss, and tt are OFTEN doubled in English. But that will be much less tedious to fix than the double letters throughout the rest of the document.

If you don't have a word processing program with decent Find & Replace, you can install LibreOffice here:

https://www.libreoffice.org/

LibreOffice is free (libre and gratis). It is available for Microsoft Windows (x86 or x86_64 [← Vista or newer]), Mac OS X (10.8 or newer; x86_64), and GNU/Linux (x86 or x86_64; deb or rpm). It has a great Find & Replace feature, and, after you've done the replacements, all the misspelled words left over will have a red underline. You can right click those misspelled words and choose the correct word from a drop-down list.

Try using this.
