telegram的windows端更新后字体发生变化已修复，可用以下方法恢复。

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
"DAOpenSans"="Microsoft YaHei UI"
"DAOpenSansBold"="Microsoft YaHei UI Bold"
"DAOpenSansBoldItalic"="Microsoft YaHei"
"DAOpenSansRegular"="Microsoft YaHei"
"DAOpenSansRegularItalic"="Microsoft YaHei"
"DAOpenSansSemibold"="Microsoft YaHei"
"DAOpenSansSemiboldItalic"="Microsoft YaHei"
"DAVazir"="Microsoft YaHei"
"DAVazirBold"="Microsoft YaHei Bold"
"DAVazirMedium"="Microsoft YaHei Light"
"DAVazirRegular"="Microsoft YaHei"
;; Priority font resolving: "Cascadia Mono", "Consolas", "Liberation Mono", "Menlo", "Courier"
;; Override monospace font:
"Cascadia Mono"="Consolas"

以上内容保存为reg文件，双击导入，重启telegram生效，原理是修改了文字映射
