blocks|key|597019|text|我的猜测是，当您更改小部件的样式表时，您的字体将更改为一个，这不支持印地语。为了解决这个问题，您需要找出Qt在系统中默认使用哪种字体，并将其设置在相同的样式表字符串中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|597020|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

My guess is - when you change widget's stylesheet your font changes to one, that doesn't support Hindi. In order to fix this, you need to find out, which font is used by Qt as default in your system and set it in the same stylesheet string.

This doesnt seem good solution, but for here through some trial and error. I am loading fonts (which to my knowledge Qt already supports) as with hello world program it works well until I add one button to UI.

What I am doing now ?
I am creating lineedit, setting font for it, and then setting a HINDI test on it. Then hide this LineEdit as I dont need it.

Because of doing all I mentioned above now my UI allows me to paste different language text on to other line edits on same UI screen - see attachment.

What I discovered seems stupid solution but without this line edit will show boxes for hindi text. I tested difference between my working hello world and non working hello world program using version control there is no difference in code, so somehow QT tool runtime forgets HINDI suddenly and then never understands it. But my work around make UI to understand HINDI and allied languages.

I have a simple QlineEdit on my UI. It allows me to enter Hindi language characters (copy from google translator and paste) - (जॉन) 

But when I change any of the style using stylesheet, for e.g. color changed to red. Now if I paste the same hindi language text (जॉन) it show cubes (boxes) in place of characters and I get output message "OpenType support missing for script"

Also I tried this using two edit boxes with one of it having color defined in style sheet, I see boxes on other edit box as well (even though I haven't touched its style at all)

There is no code required, just create hello world program, in designer add a editbox, defined 1 or more style e.g. color in stylesheet and try paste HINDI language characters "जॉन"

Could anyone help me on this.

我的UI上有一个简单的QlineEdit。它允许我输入印地语字符(从谷歌翻译器复制并粘贴)- (जॉन)但是当我使用样式表更改任何样式时，例如颜色更改为红色。现在，如果我粘贴相同的印地语文本(OpenType support ) (जॉन)，它会显示立方体(方框)而不是字符，并得到输出消息“script missing...
