Re: A basic question on encoding Latin characters

It is still not a problem. XML requires every instance of '<' where it could be
interpreted as the start of a tag to be quoted as "&lt;", so if you wanted to
use the combining character sequence it would have to be as "&lt;&#x0338;".
(actually, the second character doesn't need to be quoted if the character set
can express it).

In detail, here is the relevant data from the file

226E;NOT LESS-THAN;Sm;0;ON;003C 0338;...
003C;LESS-THAN SIGN;Sm;0;...

LESS-THAN SIGN is a base form (type 0).
COMBINING LONG SOLIDUS OVERLAY is a combining mark (type 1).
So in Normalization Form C, they merge to form 226E.

If people have any questions as to the types of characters, they can always just

pull up the data files on their browser to look at them directly:
