Public bug reported:

Lao line and word break support is needed to properly render Lao text on
various applications, as Lao typically doesn't uses spaces between
words, but rather mostly uses spaces like punctuation, a way to split
phrases.

An example of this is at
http://laosabbathschool.com/development/ssd/site/blog/comprehensive-
zwsp-test/

This text contains no zero-width-spaces, which are commonly used as a
workaround.

If you visit that page with the latest Google Chrome, an iPhone 8.1, or
Android 5.0 device, it'll probably look fine. The the current version of
LibreOffice also handles the text very well, if copied and pasted into a
document, and even includes word counts (may require setting the CTL to
Lao). But with other software (kate for instance), you'll see that the
lines are not equally distributed, and sometimes requires horizontal
scrolling. This creates problems with various applications, such as text
editors, email programs, and anything that renders text on multiple
lines.

Copy and paste the example text to various applications, and you will
see how they handle it. If those applications relied on the system's
version of ICU, an update to ICU 53.1 or greater should take care of
that problem. If they embed their own, then it may or may not work,
depending on what version they included. But at least the update should
help several programs support Lao text.
