Re: Problem : japanese-fonts (vlgothic-fonts-20090204-2.fc10)

But in fact if I write with vlgothic it's good. Also, if I force the system with vlgothic is also good. The problem would be DejaVu Sans (think) That would be very awkard since DejaVu doesn't have any CJK glyphs. What's happening is that for your Sans font selection, it will get translated by rules in the fontconfig configuration files (basically a list of fonts telling what to use for Sans), and it chooses the first font in the list that's capable of showing the displayed script. So in your case it chooses DejaVu to display Latin, and when it encounters CJK glyphs, fontconfig has no idea whether it's Chinese or Japanese, and so selects the first font in the list with the necessary glyphs, and that's a Chinese font. The solution is to move your VLGothic font above the Chinese font in that list.

Precisely, full specs of hinting instructions, such as parameter explanation of all hinting instructions You'll have to go through that documentation mentioned on the page above. The hinting tutorial on that page which I started myself once never really got far, but it can give some idea. - If a CVT table has no comments on each value, do I have to do reverse engineering and how should I begin? Yes, you'll have to do some reverse engineering. It takes a considerable amount of time, since you basically have to read the hinting of a lot of glyphs. Your goal is to get a table of values you may encounter in normal glyphs (and that for each style). http://www.dejavu-fonts.org/wiki/index.php?title=Control_Value_Table lists it for DejaVu and many fonts have values for the same things in their CVT so gives an idea what to expect in Liberation. There are usually many values in the CVT that don't really matter to you if you just want to hint some glyphs. As Mailhot's previous emails on new font packaging guidelines, he often let us refer to Dejavu Fonts. I am wondering if I could catch up any of Dejavu devs who don't mind kindly provide valuable info of hinting? Here we go then :-) When I'm online, find me at #dejavu or ##fonts on IRC if you have questions.

If you are available, it would be fantastic if you briefly tell me in 10 -15 steps? What do you want to know exactly? My previous experience was trying to fix hinting problems, I went into hinting instruction window of a glyph. Then looked at the hinting instructions and see if there are any problems. I am wondering about what extra you have done to a font, rather that just modifying hinting instructions. You want a list of everything I've done with a font so far? :-p In respect to hinting in DejaVu the only things you can really do is editing existing instructions and creating new ones for the new glyphs. Over the time CVT values were added, the fpgm table was altered etc. After editing it's just a matter of testing it out -- you can do that within FontForge itself (grid fit), and then check in gwaterfall if there's not a weird problem at some size. Only the first person who wants to work on the hinting needs to do some work to know what the important CVT values are, and that's basically reading the existing instructions and write down which values are used where. It's usually pretty straightforward (if it moves a point on the right side of the stem of I horizontally when the reference point 0 is a point on the left side of that stem, then you know it's the horizontal stem width). But that requires understanding of the instructions of course (I don't know how much you know about it, http://www.dejavu-fonts.org/wiki/index.php?title=Hinting_tutorial/Example:_Hinting_L should give you the real basics if you're completely new). For hinting that's it really. I don't know what more you're expecting? ___ Fedora-fonts-list mailing list Fedora-fonts-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-fonts-list

Re: Analysis of combining diacritics support
On Tuesday 22 July 2008, Vasile Gaburici wrote: - DejaVu has positioning issues The positioning issue you see is likely a problem that T doesn't have a cedilla anchor in Serif. Normally an easy fix. That's why renderers should have fall-back options (like Qt has). Usually these fall backs will give less optimal results, but a lot better than nothing at all. Given that commercial fonts suck at this, I suspect we won't see the combing method used often. Not for Romanian anyway. It seems however that adding diacritics to arbitrary letters is useful in Dutch, according to this post anyway: [http://www.typophile.com/node/2764#comment-99219] Well, we would need them only in one rare case (when we emphasize the ij sound, like íj́ ) As a result the accent on the j is usually dropped, so it becomes íj, but official spelling rules want both accents. Anyway, there are many languages with Latin script that are much worse of (a lot of African languages for example), since combining diacritics are needed in an awful lot of other languages. Because font foundries select their character sets based on the market demand, they don't see a lot of merit in adding glyphs and features that are only needed there. So, that's basically something we should exploit with free/open fonts, to give us the lead in these areas.

I guess you just need to be used to how FontForge handles OpenType? I
don't think it looks that hard to do. It used to be much harder as well
before George completely redid OpenType handling :-).
But true, you need to be familiar with lookup tables, while I guess you
just want to be able to select a glyph, and click some buttons saying:
I want feature locl for languages latn{ROM} and latn{MOL} and
substitute it with glyph X. And actually, it already works like that,
if you made the lookups and lookup subtables. It only makes sense to
put these together in tables like that. If you have a list of glyphs
you substitute in certain languages and suddenly think you need one
other language you don't have to change all previous lookups, just
change the language list in the data.
btw, there is a Copy lookup data entry in the FontForge edit menu
that could ease the pain having to redo everything for each font.
