TBrowser non-ascii text scrambles on windows

[shangjiaxuan]

It seems the new html-based TBrowser does not handle non-utf8 environments, and will show scrambled text in file selection, and selecting scrambled text as directory will not succeed. The old one, now TRootBrowser, however, is not supported in 64 bit windows.

It is impossible to run specific apps on specific code page in win8+ (no locale setting built-in), but there is a new setting that may allow apps to run in utf-8 no matter what (my account cannot post link yet):

Use UTF-8 code pages in Windows apps - Windows apps

It may solve the problem of code page issues on new TBrowser in newer versions of windows.

Tested to work on win10 Build 19041, with the following xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1">
  <assemblyIdentity type="win32" name="ch.cern.root" version="6.0.0.0"/>
  <application>
    <windowsSettings>
      <activeCodePage xmlns="http://schemas.microsoft.com/SMI/2019/WindowsSettings">UTF-8</activeCodePage>
    </windowsSettings>
  </application>
</assembly>

And the following command:

mt -manifest C:\Users\shang\Documents\Source\root-utf8\utf8-execution-root.xml -outputresource:C:\root_v6.26.06\bin\root.exe;#1

First, welcome to the ROOT Forum!

@shangjiaxuan

The old one, now TRootBrowser, however, is not supported in 64 bit windows.

FYI, we now provide Win64 builds…

Otherwise, you’re right, and thanks for providing the solution! We will see how to integrate that in future builds.

Cheers, Bertrand.

I tried the old TRootBrowser in provided older 6.26/02 build and seemed broken on x64. That’s why I thought it had problems.

It seems 6.26/06 still have this problem. The window will not show anything on x64 (blank screen).

Weird, I’ll check

I have no problem with the version 6.26/06 of TRootBrowser and RWebBrowser

A screenshot of my system with this problem:
Scrambled:

With manifest, not scrambled:

Blank screen in 64 bit, scrambled in root file open. (with or without manifest, 32 bit is not blank):
