How to remove short vowels from Arabic strings

sometimes you might want to search Arabic text. Don't just let the user decide on the search string. You never know how your target string is spelled (short vowels are optional).

One way of doing it is to keep a devowelized string of the target and whenever a user wants to search it, strip all short vowels again.

To do so use this method:

# in order to have icu support in sqlite you need to enable it via compile options.
# install the icu dev package on your system and download the source files from sqlite
# unpack and enter the source dir

# on a mac I had to do this to compile:
brew install icu4c

CFLAGS=`-I/usr/local/opt/icu4c/include -O3 -DSQLITE_ENABLE_ICU` CPPFLAGS=`icu-config --cppflags` LDFLAGS=`-L/usr/local/opt/icu4c/lib icu-config --ldflags` ./configure

# I had to add the path to the icu libs

If you'd like to use `"*y` and `"*p` in neovim you have to make sure it works across the stack.

These steps are necessary:

  * Have xsel installed
  * enable `X11Forward` in your remote sshd.conf
  * disable `X11Localhost` in the same file
  
Then restart your ssh connction with the -Y flag and make sure to restart tmux otherwise you might get errors because $DISPLAY might not yet be set.
