Since this request was made, Khmer Software Initiative has released a new font
KhmerOS Siemreap that is very much more consistent with a Sans Serif typeface
than other Khmer fonts.

This font is released under the Lesser GPL license.

In addition to the characters identified earlier, there are roughly 40
ligatures and 33 alternate characters that should be substituted whenever the
non-printing coeng (U+17D2) appears before consonants U+1780 - U+17A2.

What are the license considerations in copying the glyphs from KhmerOS
Siemreap? These match DejaVu Sans fairly well, although some adjustment might
need to be made in height (minor), width (insignificant) and stroke (minor).

Consonant clusters in Khmer put the second consonant under the first. Some
vowels go below the consonant, and below that subscripted consonant in a
cluster. Other vowels go above the first consonant and sometimes diacritics are
used that go above that.

Consequently, the vertical space for Khmer needs to be somewhat taller than for
Latin characters.

What adjustment would need to be made to keep line-spacing normal for LGC text
but considerably increased for Khmer text when both appear in the same
document?
