| No; this isn't a *definition* of \b .
| It is a *declaration* of what to do, under certain circumstances.

| In the case at hand, it is actually irrelevant, since the

|
| These later declarations take precedence:
|
|   \DeclareUTFcomposite[\UTFencname]{x1E48}{\b}{N}
|   \DeclareUTFcomposite[\UTFencname]{x1E49}{\b}{n}
|
| so that with the combination of accent \b  and letter  n
| XeTeX is asked to use  \char"1E49 .

So, I don't know what to do: if I disable xunicode, I can get
\char"1E49, \char"1E48, but some other char are missing (for instance
\i, and if I need \=\i it is impossible to have it with a "i" without
dot...)

BTW I noticed that diacritics are not correctly displayed when you use
xunicode; for instance \d (ie underdot), the dot is written under the
right of the character with some fonts: palatino linotype, times new
roman...., in a better position with some others: junicode. This
behaviour is slightly corrected if you add xltxtra.

Last: can someone give me the name "nice" fonts with all possible
diacritics, and features like "rare ligatures", oldstyle numbers, and so on.

Is it possible to know what features are available in one font?

Thanks.
