On cpdn we have a team trying unsuccessfully to make its name, Universität der Bundeswehr München, display properly on its Boincstats page:

​http://www.boincstats.com/stats/team_graph.php?pr=cpdn&id=5624

though on cpdn it displays correctly:

​http://climateapps2.oucs.ox.ac.uk/cpdnboinc/team_display.php?teamid=5624

Cpdn member Richard Rodway says

It's definitely UTF-8 that's appearing on the boincstats pages and it looks like the correct (2 byte) UTF-8 sequences are being used. Unfortunately the page is being served as an ISO8859-1 page and as a result the 2 byte sequence is not being interpreted as one character, but as two. This apparently is being done by the server since it's specifically encoding these bytes to appear correctly as 8859-1 characters, so changing the page encoding in the browser will not work! (It's using html entities to render the characters)

I notice that the climateprediction page for that team is also a 8859-1 encoded page, but in this case the correct code values are being used. 'ä' is encoded as the single byte 0xE4 in 8859-1 and this is being used on the cpdn pages.

I don't know how the team name is getting propagated to the boincstats servers, but something in the way has translated that to UTF-8. The encoding for 'ä' in UTF-8 is the 2 byte sequence 0xC3 0xA4. However if you read that as 8859-1 then instead of translating that sequence into the one character U+00E4 (ä) it gets viewed as the 2 8859-1 characters 0xC3 and 0xA4. 0xC3 is a Ã, 0xA4 is a ¤ . The server is reading the UTF-8 sequence, and probably then storing it unchanged in the database. Then whenever a page is generated, it's reading that data from the database and assuming that it is ISO8859-1

To fix the problem you need to make sure that whatever is sending the team names to boincstats is doing so in an encoding that boincstats understands. There's nothing at all wrong with UTF-8, and my preferred solution is for boincstats to use UTF-8 in its webpages and database (or at least some variant of Unicode in the database). Not only would this fix this problem, it'd also allow teams (and names) to use any character. Such as Japanese or Korean characters... Which is quite impossible in 8859-1, there's only 256 characters in that characterset, as opposed to about 1.1 million in Unicode... (although I think only about 150,000 are currently in use).

The cpdn discussion is here - one sees that none of the usual solutions work:

This problem must affect teams from all projects. Any hope of a solution?

Posted by: Date: 12:14 AM 12-18-2005 Boinc CC V 5.2.6 - 5.2.13 passes its open file descriptors on to the applications when the applications are started. This includes open network sockets and connections.

Proposed fix: Close all excess file descriptors after fork, before exec loads the application.

Posted by: Date: 1:54 AM 12-18-2005 set close-on-exec flag for descriptors in boinc_socket() and boinc_fopen(); hopefully this gets them all.

Posted by: Date: 12:26 AM 05-06-2006 This bug is still present in Boinc CC 5.4.9 See the attached output of lsof for the simap applikation. The application holds a descriptor to the socket for remote gui rpc and one for the aktive connection from BoincView? to the CC.

Posted by: Date: 7:23 AM 01-06-2006 Some people don't like the balloon tooltips the manager generates in the system tray. Provide an option (command-line flag such as --no-tooltips or a persistent menu option) disabling them for those users who don't like them
