Telegram在升级到18.10版本后，波斯字体发生了变化！

21

我的 Telegram 字体在升级到 18.10 版本后发生了变化！有人知道为什么会这样吗？

当我在命令行中打开Telegram时，出现了以下错误：

答案：

我通过将~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf的内容更改为以下内容来解决了这个问题：

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <dir>/usr/share/fonts</dir>
    <dir>/usr/local/share/fonts</dir>

创建一个名为fonts的目录，放在fc-custom-1.conf文件旁边，并将一个名为B_Nazanin_YasDL.com.ttf的字体粘贴到该目录中。

你使用的是哪个版本的Telegram？请查看此链接https://askubuntu.com/questions/954165/properly-update-telegram - JoKeR

@JoKeR Telegram 1.4.2 - Alireza Afzal Aghaei

你应该尝试降级你的字体库。我也在尝试同样的事情。如果成功了，我会告诉你的。 - Sepehr GH

这是我为波斯语解决此问题的方法：

关闭 Telegram
创建目录：~/.fonts
添加一个带有不同字重的字体 [我使用了Vazir]
创建文件：~/.fonts.conf 并将以下内容添加到其中：

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
    <match target="pattern">
        <test name="family" qual="any">
            <string>sans serif</string>
        </test>
        <edit mode="assign" binding="same" name="family">
            <string>Vazir</string>
        </edit>
    </match>
    <dir>~/.fonts</dir>
</fontconfig>

清除字体缓存：

fc-cache -f -v

rm -r ~/.cache/fontconfig_11

现在打开Telegram :)

- RuNo280

2对于在Debian-XFCE系统中的便携版Telegram应用，只需将Vazir字体包复制到.local/share/fonts/目录下，然后重新启动Telegram即可解决问题。 - EsmaeelE

只需将其删除，然后从Ubuntu存档中安装即可。

sudo apt install snapd

sudo snap install telegram-desktop

更新：自Telegram 1.8.4版本起，不再存在fc-custom-1.conf文件，因此这里提供另一种解决方案（假设Telegram二进制文件位于/opt/Telegram/Telegram目录下）：

创建一个Telegram字体的配置文件（路径可选）：

touch /opt/Telegram/fonts.conf

并将以下内容添加到其中： Vazir ~/.local/share/fonts /usr/share/fonts/ 我使用了Vazir字体，如果你想使用其他字体（例如Tahoma），你必须将Vazir更改为Tahoma。

修改位于~/.local/share/applications/telegramdesktop.desktop的Telegram .desktop文件为：

[Desktop Entry] Version=1.0 Name=Telegram Desktop Comment=Official desktop application for the Telegram messaging service TryExec=/opt/Telegram/Telegram Exec=env FONTCONFIG_FILE=/opt/Telegram/fonts.conf /opt/Telegram/Telegram -- %u Icon=telegram Terminal=false StartupWMClass=TelegramDesktop Type=Application Categories=Network;InstantMessaging;Qt; MimeType=x-scheme-handler/tg; Keywords=tg;chat;im;messaging;messenger;sms;tdesktop; X-GNOME-UsesNotifications=true X-Desktop-File-Install-Version=0.23

将您的字体放置在~/.local/share/fonts中。

谢谢！它完美地运作。 - H. Najafi

只有这个答案在Telegram 2.0.1上有效。 - Mahdi Abdi

这个解决方案对我有效。 - Milad Khajavi

只需在终端中键入以下命令，即可简单地删除此文件：

killall Telegram && rm -rf ~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf

- Hayder Ctee

对我没有起作用 - Maryam Homayouni

关闭 Telegram 应用

将字体复制到一个目录中（例如 cp Tahome.ttf /home/alice/Telegram）

vim ~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf

移除所有 <dir> </dir>

添加一个 <dir>path_to_your_font_dir</dir>

然后将所有字体名称更改为您的字体名称。

我的配置如下：

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
        <dir>/home/alice/Telegram</dir>
        <dir prefix="xdg">fonts</dir>
        <match target="pattern">
                <test qual="any" name="family">
                        <string>Tahoma</string>
                </test>
                <edit name="family" mode="assign" binding="same">
                        <string>Tahoma</string>
                </edit>
        </match>
        <cachedir>/var/cache/fontconfig_11</cachedir>
        <cachedir prefix="xdg">fontconfig_11</cachedir>
        <cachedir>~/.fontconfig_11</cachedir>
        <match target="font">
        <edit mode="assign" name="antialias">
                <bool>true</bool>
        </edit>
        <edit mode="assign" name="embeddedbitmap">
                <bool>false</bool>
        </edit>
        <edit mode="assign" name="hinting">
                <bool>true</bool>
        </edit>
        <edit mode="assign" name="hintstyle">
                <const>hintslight</const>
        </edit>
        <edit mode="assign" name="lcdfilter">
                <const>lcddefault</const>
        </edit>
        <edit mode="assign" name="rgba">
                <const>rgb</const>
        </edit>
        </match>
</fontconfig>

那么

fc-cache -f -v
rm -r ~/.cache/fontconfig_11

打开 Telegram 应用程序 :-)

尼玛说的方法是可行的，但最好的方式是安装Telegram的snap或flatpak版本。

首先清除你当前的安装：

sudo apt purge telegram-desktop

然后删除以下文件夹：

sudo rm -rf ~/.local/share/TelegramDesktop

然后你可以简单地按照以下步骤进行：

sudo apt install snapd && sudo snap install telegram-desktop

不是一个好主意！尝试解决问题而不是掩盖它们。 - SAYE

只需安装一个波斯字体，如Shabnam或其他你喜欢的波斯字体，并重新启动系统。

我在将Kubuntu 18.04升级到18.10后遇到了完全相同的问题！

为了弄清楚这个奇怪的字体是什么，我浏览了一下发现Telegram使用的是KacstArt字体（可能是因为它在获取所有系统字体时，这是列表中的第一个字体）。

我通过将Telegram字体搜索路径限制在一个单独的文件夹中，该文件夹只包含我想要的字体来解决了我的问题。具体步骤如下：

有一个字体配置文件~/.local/share/TelegramDesktop/tdata/fc-custom-1.conf，打开它。

将其中所有的<dir>和<cachedir>条目注释掉（简单地用包裹起来）。

在文件开头的<fontconfig>后面添加一个<dir>[你想要的文件夹]</dir>，其中[你想要的文件夹]是指向只包含你想要的字体的自定义文件夹的路径。（例如，我在~/.local/share/TelegramDesktop/tdata/myfonts中创建了一个文件夹，然后在那里添加了tahoma.ttf和tahomab.ttf）

重新启动 Telegram 并享受吧。
