Webkit 下中文字体问题的解决 | Solution to the problem of unexpected Chinese fonts in webkit

也许是仅局限于webkitgtk

之前尝试epiphany的时候就发现了这个问题，但是由于epiphany对我来说只是一个备用浏览器，所以没管它。 今天给empathy搞adium主题时这个问题再次蹦了出来，我决定干掉它。

https://bugs.launchpad.net/ubuntu/+source/webkit/+bug/502610 这里有些讨论，里面有个链接指向了改fontconfig的办法，但是我想我这里并不是这个问题，因为我在~/.fonts.conf里已经之定好了我希望的中文字体（主要是serif, sans-serif, monosapce这几个列表）,我还是觉得这个是webkit的问题。

empathy有个选项可以开启webkit debug模式：/apps/empathy/conversation/enable_webkit_developer_tools 我用它查看元素，发现字体总是sans...目前解决方法是手工改css，找到.msg的定义，加入 font-family: "font name 1", "font name 2";

另外就是epiphany，虽然它不能给各个语言指定字体，但是好歹支持用户css，于是加入如下内容：

@charset "UTF-8"; // 如果字体名有中文
* {
font-family: "font name 1", "font name 2" ! important;
}

这样问题基本可以解决



Or maybe it's only a bug for webkitgtk, I'm not sure.

Days before I encountered this bug when I was trying epiphany, but I didn't pay much attention on it since I use it only as a backup one. However today the bug came out and started to trouble me again when I was applying an adium theme for empathy, and then I decided to get rid of it.

There are quite some discussions in https://bugs.launchpad.net/ubuntu/+source/webkit/+bug/502610 , and someone there provided a solution that to modify config files of fontconfig. But I think it's not the case at least for me, since I've specified my preferred fonts of the generic font families (serif, sans-serif, monospace). I think it should be webkit's fault.

Enabling "/apps/empathy/conversation/enable_webkit_developer_tools" will enable the debug mode of empathy, where I can inspect the HTML elements (that's cool!), I found the font of messages are all "Sans", and I got no solution except for manually modifying the css file of the theme, just add the following lines in the ".msg" block

font-family: "font name 1", "font name 2";

About epiphany, I wonder why I cannot specify font for different languages/charsets just like firefox, but at least it supports user specified css, so I created one with the following content:

@charset "UTF-8"; // since the name of the font I'm using contains Chinese characters
* {
font-family: "font name 1", "font name 2" ! important;
}

and it works like a charm :)

Determine Perspective Lines With Off-page Vanishing Point

In perspective drawing, a vanishing point represents a group of parallel lines, in other words, a direction. For any point on the paper, if we want a line towards the same direction (in the 3d space), we simply draw a line through it and the vanishing point. But sometimes the vanishing point is too far away, such that it is outside the paper/canvas. In this example, we have a point P and two perspective lines L1 and L2. The vanishing point VP is naturally the intersection of L1 and L2. The task is to draw a line through P and VP, without having VP on the paper. I am aware of a few traditional solutions: 1. Use extra pieces of paper such that we can extend L1 and L2 until we see VP. 2. Draw everything in a smaller scale, such that we can see both P and VP on the paper. Draw the line and scale everything back. 3. Draw a perspective grid using the Brewer Method. #1 and #2 might be quite practical. #3 may not guarantee a solution, unless we can measure distances/p...

Qubes OS: First Impressions

A few days ago, while browsing security topics online, Qubes OS surfaced—whether via YouTube recommendations or search results, I can't recall precisely. Intrigued by its unique approach to security through compartmentalization, I delved into the documentation and watched some demos. My interest was piqued enough that I felt compelled to install it and give it a try firsthand. My overall first impression of Qubes OS is highly positive. Had I discovered it earlier, I might have reconsidered starting my hardware password manager project. Conceptually, Qubes OS is not much different from running a bunch of virtual machines simultaneously. However, its brilliance lies in the seamless desktop integration and the well-designed template system, making it far more user-friendly than a manual VM setup. I was particularly impressed by the concept of disposable VMs for temporary tasks and the clear separation of critical functions like networking (sys-net) and USB handling (sys-usb) into the...

ESP32S3: Flash Encryption and Secure Boot

Flash encryption and secure boot are useful security features for ESP32S3 chip. While not perfect, they definitely make it harder to extract the secrets in the chip. However, it is tricky to enable both features at the same time. The topic is actually discussed in the official documentation: ESP32S3 Security Features Security Features Enablement Workflows Especially, the second one mentioned it is recommended to enable flash encryption before secure boot. But I still find the documentation confusing. In the end I was able to successfully enable both, here's my findings. My Understanding After my adventure, here's what I think could have worked. WARNING, this is untested. Follow  Security Features Enablement Workflows : Burn all the keys, as long as their purpose eFuses and read/write protections Burn other security eFuses, but DO NOT burn ENABLE_SECURITY_DOWNLOAD in the middle, which is mentined at the end of the instruction for both flash encryption and secure boot.
