just done it: you can grab it from [1]

Haven't done this since I've stripped only the tarballs

actually I meant DejaVuSans*.ttf

Some weird messages happened during the stripping but let's just
move on for now :)
Here's the stats for usr/share/fonts:

The size of mini.iso went from 10674176 bytes to 9512960 bytes
I took some screenshoots using Attilio's tool and to me looks
like things changed the right way: I'd like to hear from native
speakers.

bengali: compare [2] with [3]
hindi: compare [4] with [5]
punjabi: compare [6] with [7]

I removed only BoldOblique. Let's say this was a minimal cleanup without
risks. Obviously we can strip alot more but we can't expect to gain alot more space:
the iso containing _only_ nazli is 8185856 bytes, so I guess we can use that as lower
limit...

If you want to avoid going through the all process of stripping the fonts, you can get
a tarball [8] with all the stripped tarballs (it's recursive :))

PS: Christian, I noticed that hi.po does not contain the "/Choose language" in the msgstr;
now I understand why it is useful
