774965 - Double click to select Chinese word not a sentence

Status: RESOLVED DUPLICATE of bug 1719535

(Core :: Internationalization, defect)

Description

[Sun]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:13.0) Gecko/20100101 Firefox/13.0.1
Build ID: 20120614114901

Steps to reproduce:

Double click on a Chinese word in page(not in <input/> element)


Actual results:

Firefox selects a whole sentence (until a Chinse comma)


Expected results:

Firefox should select a word not the sentence and neither a Chinese character.
Just like behavior of Google Chrome.
And if triple click, Firefox should select the sentence just like what it does now when double click.
It will be useful for non-English users.

The screenshot shows different behavior between Firefox and Chrome.

I think that Google Chrome uses icu lib to detect non-English word.

Comment 5

Additional that the best word segmentation in the test case is:
这是/一段/测试/文字，这是/第二/段/测试/文字。

In Bug 390048, it seems that something has been done before.

This bug is fixed by bug 1719535. Tested on Firefox Nightly 2023-08-07. When I double-click on "测试", it selects "测试" instead the entire sentence "这是一段测试文字".
