[kbd] Please support narrow no-break space (U+202F)

I wrote a simple script from this which update all fonts.
This fix this bug for me and, as an extra bonus, it also implement most
Unicode spaces.

In the process I noticed that "Lat2-Terminus16.psfu" already supported
all spaces, except narrow no-break space.
I also noticed that some fonts have some duplicate mapping (eg.
"UniCyrExt_8x16.psf" have "Unicode: [00000020];[000000a0];[000000a0];")
My script cleans all those things.

You have to execute this script in the font directory (so from
"$KBD-SOURCE-DIR/data/consolefonts") and then you will find updated
fonts in "/tmp/psf".
Then you just have to replace old ones in the src-dir and make/make
install.


Here his the script: 

########################################
#!/usr/bin/env bash

DIR=/tmp/psf/txt
rm -rf /tmp/psf
mkdir -p $DIR

## For each font in the current folder...
for i in $( find . -regex '.*psfu?' -not -name "README*" | cut -c3- );
do
    ## Convert to txt
    psf2txt $i >> $DIR/$i.txt

## Match the Unicode line of the space glyph and replace it to support
all kind of Unicode spaces.
## Store the result in a '.edit' file.
    sed "/\[00000020\];/c\Unicode:
[00000020];[000000a0];[00002000];[00002001];[00002002];[00002003];[00002004];[00002005];[00002006];[00002007];[00002008];[00002009];[0000200a];[0000202f];" $DIR/$i.txt > $DIR/$i.edit

    ## Convert back to psf
    txt2psf $DIR/$i.edit > /tmp/psf/$i
done
## We did it! \o/

What are your thoughts?
