Description

« Hide

In a new search engine, it is not possible to retrieve it in Japanese.

1. A new search screen is displayed
2. Japanese is input to the input column.
3. "Search" button is pushed.

It operated normally until Second Life 1.18.5(3) was released.
Similar trouble is occurring in "Release Candidate" now.

The problem on the search engine side.

Just to be sure the problem is in the search engine, and not in how the client sends data to the search engine, could you test your search here?

http://www.lexneva.name/sl/search.html

That form submits searches directly to the new search system.

Hi, Lex.

1. Japanes (日本語) is input to the input column.
2. Search button is pushed.

[Result]
-------------------------------------------------------------------------------
Your search - { - did not match anything we could find within Second Life. Nothing was found in Second Life containing "{". Suggestions:
Make sure all words are spelled correctly.
Try different keywords.
Try more general keywords.

It was not possible to retrieve it.

repro of another way:

1. you can see japanese "あ"(HIRAGANA LETTER A) at unicode.org
http://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=3042
>Unihan data for U+3042
>Glyphs
>Your Browser
>あ
>Encoding Forms
>UTF-8
>E3 81 82
2. copy character from "Your Browser" column to clipboard.
3. open secondlife viewer,
open "Search Second Life" window by Ctrl+F,
select "All" tab.
4. copy character from clipboard.
press Search Button
5.you can see this message.
(note that the character code in UTF-8 of "あ" is E3 81 82)

Your search - FFFFE3 FFFF81 FFFF82 - did not match anything we could find within Second Life.

to Lex
You should add the following lines to a header and should set a character code to UTF-8.
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

A retrieval word is "日","本","語".
It should be converted with %E6%97%A5%E6%9C%AC%E8%AA%9E
but if encoding is set as Shift-JIS, It is converted with %93%FA%96%7B%8C%EA

It's not Search Engine's problem (ya, there is no reason that google engine doesn't support multilanguages

. With firefox, march's first URL(UTF-8 type) cue returns fine results. it seems SL client couldn't handle UTF words well (as usual...)

Seems to repro for me.

By the way, there seems to be a lot of people watching, but nobody voting for this... Voting helps people know to prioritize this higher, so don't forget to do both.

To clarify, right now, if I copy and paste "日本語" into Lex's form, it seems to work, but when I do it in the viewer, I get the same problem. Does this mean this should be moved to VWR? (I can move, if that should be done.)

Better description, adding "Search" to components affected.

Patch attached.

search_text needs to URL encoding correctly.
But the value of the range to 0x80 to 0xFF did not care
when processing each byte in URL encoding process.
Then A sign extend is the cause,
the result became strange when MSB(Most Significant Bit) is 1.
@see below:
http://en.wikipedia.org/wiki/Sign_extension
http://ja.wikipedia.org/wiki/%E7%AC%A6%E5%8F%B7%E6%8B%A1%E5%BC%B5

Example:
In the case of "char c = 0x81",
if increases the word length to 32 like "static_cast<U32>(c)"
is set to 0xFFFFFF81 and URL encoded result is not "%81" but "%FFFFFF81".

With the current source, URL encoding process is embedded in the search process.
But URL encoding process is a general-purpose process.
So, I divided the function into two.
(I wonder why "std::setw(2)" at "LLURI::escape" looks doesn't work?)

I think Sign extension is different with the CPU/OS architecture and compiler.
my environment is Core2Duo E6600 + WindowsXP Home SP2(32bit) + VC++2005 ExpressEdition.
We need the more test case.

to Nock, Celierra
Yes. This is not the issue of a server but an issue of a viewer.
and should be changed from SVC to VWR.

Replace spaces with "+" for use by Google search appliance. (I just copy it from original source),
and add some comments.

I created a VWR version of this issue.

Thank you for your help reproducing the problem and providing patches. I have fixed this for the next 1.18.6 release candidate.

I changed your patch slightly. The LLURI portion of the patch needs to be static_cast<S32>(static_cast<U8>(c)), otherwise some normal escaping does not work correctly.

I have changed llpaneldirfind.cpp to use LLURI::escape() and added a unit test for escaping the cedilla in Français.

Japanese searches like 日本語 appear to function as well.
