Subject Nutch-18 illegal chars in urls: Not sure what the problem is
Date Wed, 26 Apr 2006 20:15:05 GMT

Was looking into nutch-18 bug that revolves around
illegal, non-ascii, characters in a url. An example of
a high bit character is 'ç' that maps to a high bit

Before applying any fix, did a brief test with 0.8
trunk. After fetching and indexing onç, I was able to search
on ç and got the following result off the browser

ç - Wiktionary
... Letter [ edit ] Translingual [ edit ] Letter Ç , ç
C with a cedilla ... visit IRC or Wiktionary:AOL . ç
... (cached)
(explain) (anchors) (more from 

So it looks like it will fetch and parse off of urls
with high bit set characters. Additionally, the
display url has the ç encoded correctly as %C3%A7. 

Is this really a bug?

Doing a similar test off of Google on keywords: "ç"
wiktionary. yields:

ç - Wiktionary
AOL users can access Wiktionary through this link
after accepting the CACERT certificate. ... Ç, ç.
"t&#643;&#601;", the fourth letter of the Albanian
alphabet. ...ç - 15k - Cached - Similar
[ More results from ]

Nearly identical, but the see that the ç is in its
decoded form, not %C3%A7.

If there's any interest in this issue, let me know.
