Let me explain. +2 is sufficient in most languages, but not in the four
languages I mentioned. In these four languages, syllables are not breakable.
One syllable may contain more than 2 characters. The reason they are not
breakable is a syllable may present on display as one glyph. Using English
letters as a faked example, "webkit" has two syllables, web and kit. In these
languages, w-e-b may be drawn vertically as a whole glyph and k-i-t drawn
vertically after w-e-b, horizontally (see below). In this case, +3 is required.
w k
e i
b t

This is what I learned yesterday. Hopefully, my understanding is correct.
