User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release) Build ID: 20130911155223 Steps to reproduce: Go to any Lao website, such as laosabbathschool.com. Lao text keeps going on and on until there is a space (Lao does not use spaces as word delimeters, but similar to punctuation.) Actual results: Lao text does not wrap. It doesn't know where to split the text. Expected results: Lao text should split words like the ICU 52.1 system now can do... (This is very similar to Thai / Khmer word wrapping / boundary analysis.) Can you all update Firefox to include the latest ICU 52.1? I am running Ubuntu, so I would think it would notice my locally installed ICU, but it doesn't. Also, there are loads of Windows and Mac systems that could benefit from this code as well.
