Same issue.

4.1 complete list of terminals
==============================
Gnuplot supports a large number of output formats. These are selected
by choosing an appropriate terminal type, possibly with additional
modifying options. See *note terminal::.
This document may describe terminal types that are not available to
you because they were not configured or installed on your system. To
see a list of terminals available on a particular gnuplot installation,
type 'set terminal' with no modifiers.
Terminals marked 'legacy' are not built by default in recent gnuplot
versions and may not actually work. @c <3 - all terminal stuff is
pulled from the .trm files

Please e-mail bug reports to the gnuplot-bugs mailing list or upload the
report to the gnuplot web site on SourceForge. Please give complete
information on the version of gnuplot you are using and, if possible, a
test script that demonstrates the bug. See 'seeking-assistance'.

5.1 known limitations
=====================
It is not possible to use inline data (e.g. plot '-' ...) inside the
curly brackets of a 'do' or 'while' loop.
X11 terminal: It is difficult to select UTF-8 fonts. Only one color
palette at a time is active for any given x11 plot window. This means
that multiplots whose constituent plots use different palettes will not
display correctly in x11.
Qt terminal: 3D rotation of polygons and surfaces can be slow; this
is strongly affected by the Qt rendering mode (see Qt documentation).
The *note raise:: and *note lower:: commands are unreliable.

5.2 External libraries
======================
External library GD (used by PNG/JPEG/GIF/sixelgd terminals, pixmap):
Versions of libgd through 2.0.33 had various bugs in mapping the
characters of Adobe's Symbol font. Dot-dash patterns are not supported
for these terminals.
External library PDFlib (used by PDF terminal, but not by pdfcairo):
Gnuplot can be linked against libpdf versions 4, 5, or 6. However,
these versions differ in their handling of piped I/O. Therefore gnuplot
scripts using piped output to PDF may work only for some versions of
PDFlib.
Internationalization (locale settings): Gnuplot uses the C runtime
library routine setlocale() to control locale-specific formatting of
input and output number, times, and date strings. The locales
available, and the level of support for locale features such as
"thousands' grouping separator", depend on the internationalization
support provided by your individual machine.
External library libcerf versions 1.8 1.9 1.10 return incorrect
results for the voigt function. Do not use.

Moreover, when the cursor is above
Next: Concept_Index, Prev: Terminal_types, Up: Top
in "5 Bugs", if I type the up arrow, I'm also sent to
"5.2 External libraries". So prev-line is affected too.
