Dear, Since Thai is in complex text language and need to work out in line-breaking area (in brief, need extra library/dictionary for line-breaking). This makes Mozilla.org to delay complete solution for line-breaking related issues in Mozilla product (Firefox, Thunderbird). Browser without line-breaking is nearly unusable for Thai people and the short-term solution is custom build with line-breaking patch/library. On Windows and Mac, there are some efforts for custom version, the downside is to rebuild them every minor release but it's only the way. On linux, the situation is different since we have packaging system like RPM/APT/YUM. Next Ubuntu Dapper will included Thai line-breaking patch for its Firefox as default. Since there are many Fedora users in Thailand (definitely more than other distros), I think this is important to ship line-breaking Firefox as well. I wish to know is this approach possible? We can use same line-breaking patch as Ubuntu, the main task should be packaging libthai (line-breaking library) in RPM form and verify. Thanks Isriya
