Dear Reader... No More Accent is an accent reduction product, which helps to remove accents. For example, an Asian lady (or any nationality) may have communication problems with her English when speaking to her friends or business colleagues. With that in mind, No More Accent teaches Accent Reduction methodologies to help in this area. In fact, No More Accent can be used in almost any situation where an accent reduction is required. Even Actors within the Entertainment Industry have turned to No More Accent as a way to lose or gain an accent of another nationality. No More Accent is available in two versions, CD-ROM and VHS Cassette Tape (PAL and NTSC formats) both can be purchased directly via the http://www.no-more-accents.com website. If you would like further information about our products or services, please contact myself when you have a moment. Best Wishes...

Let me make it clear. The conflict is not inside XFree86 but between RH8's gb18030.2000-1 on the one hand and Sun's and Mozilla's gb18030.2000-1 (and what James Su and Romland Mainz proposed) on the other hand. It's regrettable that your patch hasn't been discussed in open forums like fonts/i18n list of XFree86 IIRC (my memory sometimes doesn't serve me well so that I may have missed it). Do you care which of two gb18030.2000-1's is included in XFree86, do you? If you don't care, you're willing to replace RH's gb18030.2000-1.enc with that based on Sun's/Mozilla's/Java's (as suggested by James Su in http://www.mail-archive.com/fonts%40xfree86.org/msg01343.html or by Roland in http://bugs.xfree86.org/cgi-bin/bugzilla/show_bug.cgi?id=441) Independent of compound text encoding, it's bad that gb18030.2000-1 has two different meanings. That's what I want to resolve here. If you agree to go with Sun's version, we won't have to worry about having to figure out which is which (although x11 core fonts become less and less important...)

[Fonts] Encodings XLFDs within sfnt
In order to preserve bitmap font names as we switch to sfnt for XFree86, I need to have fonttosfnt put the original font name in some place where mkfontscale can find it. The proper way would be to formally define a new sfnt table, for example ``XF86''. However, I think it is simpler and quite as reliable to put a non-standard signature in some standard place. I'm currently tempted to use the ``comment'' string in the ``name'' table. I could generate it to be XFree86 font, original name was -misc-fixed-... and then check for this string. Comments? Better ideas? Juliusz ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts
Re: [Fonts] Re: two different gb18030.2000-1 : Sun/Mozilla/Java vsRH
I want to make one point clear, that is *.enc encoding files are used by fontenc layer only, adding gb18030.2000*.enc doesn't mean telling XFree86 how to handle gb18030 codes in all parts, but in fontenc layer(FreeType module) ONLY. Looking at Sun's gb18030.2000-1, they seem convert all four-bytes into two-bytes starting from 0x, then process them as 2 two-byte inside, when displaying it, fontenc will look up gb18030.2000-1 to display the font. There is no conflict whatsoever, just like i said, totally depends on how to process them inside encoding part.

[Fonts] Bitmap-only SFNTs: initial code in CVS
It is now possible to use bitmap-only SFNTs in XFree86. There is very little left to do at the server level, some more work is needed at the level of fonttosfnt and mkfontscale. 0. Check you've got the right version of XFree86. $ cvs log xc/lib/font/fontfile/fontdir.c | grep 289 289. Twisting fontfile.c and fontdir.c to be able to pass all fonts (bitmap 1. Apply http://bugs.xfree86.org/cgi-bin/bugzilla/show_bug.cgi?id=491 and rebuild mkfontscale. 2. Make a directory full of fonts. $ cd /tmp $ mkdir fonts $ cd fonts $ cp /usr/X11R6/lib/X11/fonts/misc/*.pcf.gz . 3. Uncompress the fonts. This is optional, but if you don't do that, the next step will take minutes rather than seconds. $ gzip -d *.pcf.gz 4. Convert all the fonts to bitmap-only sfnt, and give them the extension ttf (for now -- see my next message): $ for i in *.pcf; do fonttosfnt -o ${i%.pcf}.ttf $i ; done $ rm *.pcf You will get a number of failures, I'm looking into that. 5. Create a fonts.dir file: $ mkfontscale -b You'll get some warnings, and some of the generated names will not be quite right. Additionally, all non-Unicode fonts will get names ending in ``microsoft-symbol''. (Fixing that will require private extensions to the sfnt format.) 6. Test the new fonts. $ xset +fp `pwd` $ xlsfonts -ll -fn '-misc-fixed-medium-r-normal--20-*-75-75-m-*-iso8859-1' | grep RASTERIZER_NAME RASTERIZER_NAME FreeType $ xfd -fn '-misc-fixed-medium-r-normal--20-*-75-75-m-*-iso8859-1' Juliusz ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts
[Fonts] Choosing an extension for bitmap-only SFNTs
I need to pick an extension for the bitmap-only SFNT fonts[1]. While these fonts use the same file format as TrueType and OpenType fonts, they do not fullfill the requirements of any of the four (!) TrueType specifications. Apple calls them ``sfnt-wrapped bitmap fonts'', pfaedit calls them ``bitmap-only TTF fonts'', and Microsoft do not call them at all. These fonts are refused by Windows XP. Because users expect files with a ttf or otf extension to contain scalable fonts, they need to have a different extension. Such fonts are used by Apple (who do not use file extensions), but not by Microsoft (who do); hence, I believe I need to pick a new one. I suggest they should have the extension ``.sfnt'', with ``.sfn'' being recognised for compatibility with 8+3 systems. Opinions collected so far: - David Dawes doesn't have an opinion either way, but he'd like me to consult with this list first. - Egbert Eich would prefer ``.sfn'' to be the default, as he believes this will lessen his support load. (He's probably right, but I dislike making MS-DOS the default.) I'll probably submit code to handle the new extension these next days, and would be glad to hear from you as soon as possible.

Hmm, an XF86 table would also allow to store unconverted BDF properties which are lost otherwise. I vote for an XF86 sfnt table.

I see that Julian also knows about .snf fonts (I think that suggestion that anyone still using them should move *into* the 1980s is a little unfair - they need to move *out of* the 1980s). Still .sfn is too close to .snf; I vote for ".sfnt". Andrew C Aitchison ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts
