<para>In text mode, <application>Links</application> cannot be
configured to use UTF-8 encoding for the terminal input/output. This
limitation renders <application>Links</application> useless as a
text-based browser in UTF-8 locales. See general discussion of this
type of issue in the <xref linkend="locale-not-valid-option"/> section
on the <xref linkend="locale-issues"/> page. The patch fixes all these
issues with an exception of Chinese locale, when there isn't an available
character set.</para>
<para>In text mode, unpatched <application>Links</application> cannot be
configured to use UTF-8 or other multibyte encodings for the terminal
input/output. This limitation renders <application>Links</application>

discussion of this type of issue in the
<xref linkend="locale-not-valid-option"/> section
on the <xref linkend="locale-issues"/> page.</para>
<para>The patch adds the <quote>UTF-8 I/O</quote> configuration option.
With this option enabled, <application>Links</application> first renders
the page using an 8-bit character set configured by the user, and then
converts from this character set to UTF-8. The opposite conversion is
applied to user input. This approach works if there is an 8-bit character
set that contains all the characters that the user considers to be
important. Such character set does not exist, e.g., for Chinese
hieroglyphs, or when it is required to display both Cyrillic and Greek
characters.</para>
<bridgehead renderas="sect3">Do I Have to Enable Graphics Support?</bridgehead>
<para>In graphical mode, <application>Links</application> displays text
correctly even in UTF-8 locales, if all characters exist in the built-in
font used by <application>Links</application>. Form submission in UTF-8
locales is handled correctly when running in X11-based (but not
framebuffer-based) graphical mode.</para>
font used by <application>Links</application>. This font contains
Basic Latin, Latin-1 Supplement (without superscripts and vulgar
fractions), Latin Extended-A, Latin Extended-B (partially), Greek,
Cyrillic and Hebrew characters. Form submission in non-ISO-8859-1
locales is handled correctly when running in X11-based graphical mode.
Input handlers for other graphics drivers (fb, directfb, svgalib) either
misinterpret non-ASCII characters in the input, or don't allow them
at all.</para>
