How to input Chinese into the edit box of slint ui

Using LineEdit can't input Chinese, How to solve this problem？

slint默认会直接加载系统字体，只要系统字体支持中文就行了，如果不支持，好像slint还提供了加载外部ttf的方法的，我忘记是哪个api了

Windows下是C:\Windows下的Fonts，只要将字体文件丢到Fonts这里面去就会支持的，如果你要编译成wasm那可能需要找到加载外部ttf的api了

这个问题和#3631 应该是同一个问题来的
1、我这边生成的是exe程序，目前输入中文是没有问题的：

2、我在slint 1.4.1源码里面找到了focus_item这个属性，但是没有暴露给外部，是WindowInner的pub属性，但是WindowInner是内部pub的Window内置属性，而Window也没有提供操作focus_item的方法，所以暂时无解，看看官方是否会更新暴露修改focus_item的api吧：

3、如果你实在是非常想让wasm支持中文，那你可以将slint下载到本地，并更改pub struct Window(pub(crate) WindowInner);为pub struct Window(pub WindowInner);，然后加载字体，最后引用本地的slint

I'm sorry. Could you elaborate a little on your environment and choice of input methods?

My system is ubuntu 22.04, using Sogou input method

I tried installing this input method, but when attempting to download the arm64 .deb from https://shurufa.sogou.com/linux I get a HTTP access denied (403).

Do you know if this issue can be reproduce with another input method?

This can be tested in a VM: https://www.udrop.com/MK9U/sogoupinyin_4.2.1.145_amd64.deb

I'm testing with the latest Slint version under Plasma 6.5.4 on Wayland, the input method is fcitx5. The renderer chosen by the test program is FemtoVG. Chinese characters can be typed into LineEdit and TextEdit under such conditions. Then I switched to LXQt 2.3.0 and found that fcitx5 cannot be activated in the same slint program's window, while it can be activated in regular applications.

Under Windows, Slint (with FemtoVG renderer) is at least working with Microsoft Pinyin.

On Android: Slint has been working with Sogou and Fcitx. However, I found another strange problem occurred in Slint 1.14.1: under some old Android versions, emojis can be shown in text views, but CJK characters are shown as rectangles with diagonal lines. My workaround is to embed a full font (like import "/usr/share/fonts/droid/DroidSansFallbackFull.ttf"), and add properties like font-family: "Droid Sans Fallback";. I haven't found such problem in Slint 1.13.1.

I'm familiar with the Fcitx input framework and don't want to try Sogou in my host Linux for now, but these are globally accessible links:
