Re: [gui-dev] LimeWire 4.2.3 international font display patch

Not necessarily: you can normalize filenames read from filesystems so that 
they will be shared easily with Windows or Unic users, and this won't 
prevent other mac users to get access to these files, or to read these 
filenames .

On the opposite, it is the fact that we keep the denormalized filenames read 
from Mac HFS+ filesystems that causes interoperability problems with other 
users (this causes no problem only for Mac users, that won't see the 
difference if they now receive normalized filenames from Windows/Linux or 
from corrected Mac versions...)

So there's no need to normalize queries or results in Gnutella, only when 
reading files from local shared directories...

Normalizing incoming results would only help reading these results on non 
MacOS systems.

And of course we should not normalize queries during query matching, but 
instead assume that all files accessible on Gnutella are normalized 
preferably in NFC form, as well as all sent queries and results... The only 
case where we will need normalization is when those strings are FIRST 
generated:
- on user input within search forms, this is the keyboard driver that 
normaly generates precomposed forms, but if not sure, we could normalize the 
user input string before processing.
- when reading or writing files, we can directly use filenames in NFC form 
on all filesystem types, including HFS+!
- when reading directories the entries should already be in NFC form, except 
on MacOS HFS+ where it will be extremely useful to reconvert these 
denormalized strings back to NFC before processing and inclusion in our 
shared library list.

So no need to modify the query routing/matching algorithms whose performance 
are already critical...
