[Netsurf-develop] Font / Unicode overview
by James Bursa
In an attempt to answer the questions that have appeared recently,
I've written a guide to fonts and Unicode support in NetSurf.

______________________________________________________________________
Fonts in NetSurf
NetSurf has support for displaying pages containing Unicode characters
that aren't normally available on RISC OS, for example accented Latin
letters, Greek, Cyrillic, Japanese, and various symbols.
The font choices let you pick a font for each of the five standard
families available to web authors (in CSS). The choices specify the
preferred font to use. If a character is not available in the chosen
font, but it's present in some other font that you have installed,
then NetSurf will automatically use it. There's no need to change the
font choices to view pages with characters that are not available in
the chosen font.
Note that you can only choose a font family. NetSurf will
automatically use weights from the family for bold and slanted text,
if available.
Installing more fonts
The fonts that come with RISC OS cover Latin (Homerton, Trinity,
Corpus), Greek (Sidney), and various symbols (Selwyn, Sidney). (On
RISC OS 3-4, only the "Latin 1" characters from the standard fonts,
which cover Western European languages, can be used by NetSurf).
If you want to display pages with other characters correctly, you'll
need to install fonts containing them. When a character is not present
in any available font, the Unicode character code will be displayed.¹
Any font supplied with a correctly designed "Encoding" file should
work. In practice, native fonts covering anything other than Latin 1
are rare. The solution is to convert TrueType fonts using TTF2f (this
currently produces fonts suitable for RISC OS 5 only).
After installing new fonts, NetSurf will need restarting so that it
detects them.
Problems and unimplemented features
* The default font is always the sans-serif one.
* Printing on RISC OS 5 doesn't work, due to lack of support in the
Font Manager and printer drivers. Printing to Postscript printers on
RISC OS 3-4 is not correctly implemented in NetSurf.
* Substituted characters are taken from the first font that contains
them, even if a character which matches the weight or slant better
is available.
* Only two weights (regular and bold) are supported, even if a family
contains other weights. The algorithm that finds weights needs
improving, for example using the heuristics given in CSS 2.1 15.6.
* Drawfile export is broken.
* Right-to-left text (Hebrew, Arabic) is not implemented.
____________________
¹ If you see the codes 0091, 0092, 0096, or others starting 009, that
indicates that the page is not specifying the character set that it
is using correctly. Installing fonts won't help. We haven't yet
decided what the best way to work around this problem is.

[Netsurf-develop] Bug report
by Anthony Hilton
I get a crash with 28 July 2006 16:45 when trying to open the default
homepage (file:///Netsurf$Dir/docs/intro_en). I have logged it in the bug
tracker - 1531051 - and attached a zip archive of the log file, but checking
the report doesn't show any attached files. Does someone want me to email the
log direct?
In case it is relevant I posted the bug report using Fresco.

[Netsurf-develop] Spurious A-circumflex
by Richard Porter
I'm getting spurious A-circumflex characters on some pages in front of
characters like the pound sign. Specifically I've filled in a form in
which I used the pound sign twice in a text area. When the updated
page showing my message comes back there's a spurious A-circumflex in
front of the pound sign (encoded £ in the source).
Is this character being inserted when I submit the form or is it done
by the web server concerned?

[Netsurf-develop] Bug 1524923 follow-up
by Keith Hopper
Greetings,
This am I have twice tried to add a follow-up to the above bug.
Sourceforge has twice said it has been registered - and then when I try to
open the bug document again says that no follow-ups have been registered.
In following up all I wanted to say was that the bug is still there in
the 23 July build and, perhaps more important, when trying to open a
document after the crash, Netsurf in attempting to load itself and load the
document crashes again - and again - until I rebooted!

[Netsurf-develop] Is it me or is it Sitemeter? (or Netsurf)
by Steve Turnbull
Hi
I use Sitemeter (www.sitemeter.com) for monitoring one of my websites,
Netsurf always seemed to have problems -- sometimes just failing to
properly render a page, even though View source showed that it was
downloaded, but a refresh would usually get it.
Recent versions of Netsurf didn't have problems (apart from cookie
issues but I understand about that) but 2 Jun 06 now completely
refuses to render even the login page properly.
When I say "refuses", actually what it's always done is put a box at
the top of the screen and the Sitemeter rotating GIF in that box. But
nothing else.
Before I report it as a bug, is this a known problem? Is it something
wrong with the server? Something else?
Kind regards
Steve

[Netsurf-develop] 192.com
by Mike Binks
Hi folks
I wonder if I am the only one who finds www.192.com extremely useful
and is frustrated by the fact that the search boxes on the home page
do not work in NetSurf.
In some previous versions you could enter details even though you
appeared to type invisible text. The last few versions do not allow
entry at all.
Could somebody who understands such things tell me whether this is a
NetSurf problem or badly written page. In the case of the latter I
would take it up with the owners. But I at least would like to appear
that I know what I am talking about.
There are other ways of using the site by moving off the home page.
Thanks in anticipation.

[Netsurf-develop] Netsurf 18 Jul 0200 build - serious error
by Keith Hopper
I have just had a request to report a serious error - which I have
done - but the current build will not let me attach the log file (The 'drop
on' text is missing from the upload icon - at least.
I have therefore submitted the bug report without attached log. The
key part of that appears to be the fatal signal report at the end - which
is short so I have attached it here.
My only other browser also crashed on sourceforge this morning so I
hope this will help.

[Netsurf-develop] image link area actual image size or not?
by brian
In the case of an image used as a link and where the image is rendered
a smaller display size than actual size, NetSurf spreads the link
reference area to cover the actual size, instead of the dims in the
code overriding the ref area. Is this the behaviour I am to expect
from an img link?
Here's a test page I culled from my own site:
http://www.adam.co.nz/test.htm
The two upper image examples in the left column have different actual
sizes, and the link generated by the upper image extends into the
neighboring column.

[Netsurf-develop] Nasty crash
by Jess Hampshire
Hi
I just managed to crash NS by chosing a theme with an up button adding
it then reverting to one without the button.
Does this need to be submitted as a bug?
(I have kept a log just in case)
