[pdftex] [OT] latex questions

[The Thanh Han]

Hi all,

while translating "the not so short introduction into latex2e" to
vietnamese, I have two latex questions:

1) codes between \begin{example} ... \end{example} are not typeset
properly. If I have some vietnamese characters in the examples, they are
typeset under the caret notation like ^^be. Using tcx instead of inputenc
fixed this problem, however I wonder why I cannot use inputenc.

2) how can I have bookmarks displayed closely to the original text, ie if
a character is avail. in PDFDocEncoding then it is written as is, otherwise
an accented letter should be replaced by its base letter. For examle, if \~\i
is not in PDFDocEncoding then it should be written out as i. hyperref seems
to ignore characters that are not in PDFDocEncoding.

Thank you in advance,
Thanh
