If you are using pdfLaTeX or LaTeX and do not specify
Then LaTeX will default to the original TeX OT1 encoding. Initially
this may not seem to be a problem, especially if writing in English,
however OT1 does not include any accented letters, so any accented
letters will be constructed using the
\accent primitive rather than
using an accented character from the font. Any words using such a constructed
accent will not be hyphenated.
Note that the
t1enc package is available in the base distribution,
which is equivalent to using the
T1 option to
fontenc however it should not
be used in current documents and is just retained for compatibility
with the first versions of the LaTeX2e documentation, which were
written before the
package was produced.
