Subject [jira] Commented: (DERBY-4492) Localized help message from derbyrun.jar has wrong encoding
Date Thu, 24 Dec 2009 09:59:30 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12794376#action_12794376

Knut Anders Hatlen commented on DERBY-4492:

This problem also appears to affect the messages touched for 10.4 (DERBY-3804). The messages
for 10.3 and earlier look fine, as far as I can tell.

Now, the garbling seems to be different in 10.4 and 10.5.

In 10.4, a word such as "Schlüssel" would be encoded as "Schl\u00C3\u00BCssel", whereas it
should have been "Schl\u00FCssel". Here, the problem seems obvious: "ü" has the codepoint
0xFC, and should therefore have the unicode escape sequence \u00FC. However, the UTF-8 encoding
of ü is {0xC3, 0xBC}, and it looks like each byte in the UTF-8 encoded sequence is inserted
as a separate codepoint. That is, ü --> {0xC3, 0xBC} --> \u00C3\u00BC --> ü.
It should be fairly easy to write a script that goes through the original patch and fixes
up this.

In 10.5, I have a harder time seeing what's going on. There, the character ü (0xFC) is escaped
as \u221A\u00BA, and ö (0xF6) as \u221A\u2202. I fail to see a pattern here.

> When I change the locale to one of the languages for which we have localized tools messages,
either by changing the system locale or by setting the derby.ui.locale property, the output
from derbyrun.jar is garbled:
> $ java -Dderby.ui.locale=zh_TW -jar derbyrun.jar
> 用法:
> java -jar derbyrun.jar ij [-p propertiesfile] [sql script]
> java -jar derbyrun.jar sysinfo [-cp ...] [-cp help] 
> java -jar derbyrun.jar dblook [args] (或是不加引數以查看用法)
> java -jar derbyrun.jar server [args] (或是不加引數以查看用法)
> $ java -Dderby.ui.locale=de_DE -jar derbyrun.jar
> Syntax:
> java -jar derbyrun.jar ij [-p Merkmaldatei] [sql Script]
> java -jar derbyrun.jar sysinfo [-cp ...] [-cp help] 
> java -jar derbyrun.jar dblook [Argumente] (oder ohne Argumente für Syntaxinformationen)
> java -jar derbyrun.jar server [Argumente] (oder ohne Argumente für Syntaxinformationen)
> Only the help message from derbyrun.jar is garbled. The other tools appear to produce
fine output, even when invoked via derbyrun.jar:
> $ java -Dderby.ui.locale=zh_TW -jar derbyrun.jar sysinfo
