Regression: engine may throw transliteration errors when running from non-ASCII
system path
-------------------------------------------------------------------------------------------
Key: CORE-5159
URL: http://tracker.firebirdsql.org/browse/CORE-5159
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 4.0 Initial, 3.0 RC2
Reporter: Dmitry Yemanov
Unpack Firebird into some non-ASCII directory and try to create some ICU
collation (or restore a backup with ICU attributes), for example:
c:\тест\firebird>gbak -r -v -p 8192 c:\firebird\test.fbk c:\firebird\test.fdb
gbak:opened file c:\firebird\test.fbk
gbak:transportable backup -- data in XDR format
gbak: backup file is compressed
gbak:backup version is 9
gbak: ERROR:arithmetic exception, numeric overflow, or string truncation
gbak: ERROR: Cannot transliterate character between character sets
gbak: ERROR:failed to create database c:\firebird\test.fdb
gbak:Exiting before completion due to errors
It works fine with FB 2.5. Stack trace for error:
fbintl.dll!Jrd::CsConvert::convert()
fbintl.dll!Firebird::IntlUtil::parseSpecificAttributes()
fbintl.dll!Jrd::getVersions()
fbintl.dll!Jrd::UnicodeUtil::loadICU()

engine12.dll!DFW_perform_system_work()
engine12.dll!INI_format()
engine12.dll!Jrd::JProvider::createDatabase()
Transliteration error happens because attributes are treated as ASCII:
charset cs;
IntlUtil::initAsciiCharset(&cs);
AutoPtr<CharSet>
ascii(Jrd::CharSet::createInstance(*getDefaultMemoryPool(), 0, &cs));
IntlUtil::SpecificAttributesMap config;
IntlUtil::parseSpecificAttributes(ascii, configInfo.length(),
(const UCHAR*) configInfo.c_str(), &config);
but in fact it includes a "filename" attribute containing ANSI characters:
p = 0x00000000004a0dab "c:\тест\firebird\intl\fbintl;icu_versions=default"
