Hello, Belcon, I think you misunderstood what Vlad meaned.
The issue Vlad mentioned is the line breaking problem.
General speaking, you're right, Vlad.
Line breaking algorithm for CJK is much easier than latins.
You can break a line between any two CJK characters.
Of course, there are some exceptions.
There are a few typesetting rules for Chinese.
For example, punctuations(U+3000 - U+303F)
can not be put in the beginning of a line.
However, the rules are not very rigorous.
You can just ignore them at this time.

No, CJK characters are not case-sensitive.
