Help with Khmer Bug/Feature

Hello,

It's been a while since I submitted a feature request here (
https://bugs.freedesktop.org/show_bug.cgi?id=59448), and I know that those
capable of added such a feature are very busy, but I thought I would ask
here to see if anyone would be willing to help.

The feature request in a nutshell:
Add an additional check-box option to turn off/on the ICU breakiterator in
Options->Language Settings->Complex Text Layout if the current CTL language
has the option for using the ICU breakitorator
Default should be enabled.

Reason for the feature request:
Some minority languages use the Khmer script (but the words and grammar are
completely different), and so the ICU breakitorator does not break the
words correctly and makes using the current version of LibreOffice with
those minority langauges impossible.

Also, the ICU breakitorator for Khmer and Thai is not 100% accurate, and so
those desiring to create documents that are 100% accurate by manually
placing zero-width spaces between words cannot do so, because the ICU
breakitorator breaks the manually broken words into smaller parts which are
then incorrect (again because the ICU breakitorator is not 100% accurate).

I don't think adding an additional check-box for CTL languages that have
the ICU breakitorator enabled would cause any trouble, and would improve
overall user experience.

Thank you for your time and consideration,
Nathan
