Chinese input method string truncated when typing into `widget.NewEntryWithData'

[Czyhandsome]

I have set FYNE_FONT to support Chinese char print, but when I use Chinese input method to type something into the entry, the string gets truncated.

Code:

package main

import (
    "fmt"
    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/container"
    "fyne.io/fyne/v2/data/binding"
    "fyne.io/fyne/v2/dialog"
    "fyne.io/fyne/v2/widget"
    "io/ioutil"
    "os"
    "path/filepath"
    "time"
)

func main() {
    err := os.Setenv("FYNE_FONT", "C:\\Windows\\Fonts\\STSONG.TTF")
    if err != nil {
        return
    }
    a := app.New()
    w := a.NewWindow("突击")
    fileName := binding.NewString()

    entry := widget.NewEntryWithData(fileName)
    entry.OnSubmitted = func(fileName string) {
        now := time.Now().Format("20060102")
        //currentDir, err := os.Getwd()
        //if err != nil {
        //    dialog.ShowConfirm("Oops!", fmt.Sprintf("Getwd: %v", err), nil, w)
        //    return
        //}
        full := filepath.Join(fmt.Sprintf("%s - %s", now, fileName))
        // 检测当前是否存在同名目录或文件
        if _, err := os.Stat(full); err == nil {
            dialog.ShowConfirm("Oops!", fmt.Sprintf("File or directory %s exists", full), nil, w)
            return
        } else if !os.IsNotExist(err) {
            dialog.ShowConfirm("Oops!", fmt.Sprintf("Stat %s: %v", full, err), nil, w)
            return
        }
        err = os.MkdirAll(full, os.ModeDir)
        if err != nil {
            dialog.ShowConfirm("Oops!", fmt.Sprintf("Fail to create directory %s: %v", full, err), nil, w)
            return
        }
        // Write to file
        err := ioutil.WriteFile(filepath.Join(full, "README.md"), []byte(fmt.Sprintf("# %s\n", fileName)), os.ModeAppend)
        if err != nil {
            dialog.ShowConfirm("Oops!", fmt.Sprintf("Fail to WriteFile %s: %v", full, err), nil, w)
            return
        }
        dialog.ShowInformation("OK", "OK", w)
    }
    w.Resize(fyne.NewSize(400, 500))
    w.SetContent(container.NewVBox(
        widget.NewLabel("Please input tuji directory name"),
        entry,
    ))

    w.ShowAndRun()
}

I also have this problem using Microsoft Pinyin input

If possible could you please help test feature/go-text branch to see if this is a problem there as well? We are working to replace the text shaping to vastly improve international support.

I also encountered this problem when using the MacOS version of Sogou Pinyin input

[andydotxyz]

@zxdstyle Can you please help by testing the feature/go-text branch mentioned above?

@zxdstyle Can you please help by testing the feature/go-text branch mentioned above?

Of course, but I didn't find the branch you mentioned

[andydotxyz]

My apologise, the branch is on my fork, https://github.com/andydotxyz/fyne/commits/feature/go-text

[zxdstyle]

After my test, the branch still has the same problem

replace fyne.io/fyne/v2 v2.1.3 => github.com/andydotxyz/fyne/v2 v2.0.3-0.20220123133908-c62fd89b6c1d

[andydotxyz]

It looks to me like it changed slightly - with the branch it works the first time, but then as more characters are added it breaks. Is that accurate?

[zxdstyle]

Indeed it is

I also encountered the problem of inputting Chinese fonts, the program crashed when inputting more characters, and the input method selection box did not follow in the input box
