Cannot use cyrillic paths for cef binaries

Hello, I am using cef4delphi to embed a browser in my lazarus (2.0.8) project.
Setting paths like this:
Code: Select all
GlobalCEFApp.FrameworkDirPath:=ExtractFilePath(ParamStr(0)) + 'cef';
GlobalCEFApp.ResourcesDirPath:=ExtractFilePath(ParamStr(0)) + 'cef';
GlobalCEFApp.LocalesDirPath:=ExtractFilePath(ParamStr(0)) + 'cef\locales';
GlobalCEFApp.cache:=ExtractFilePath(ParamStr(0)) + 'cef\cache';
GlobalCEFApp.UserDataPath:=ExtractFilePath(ParamStr(0)) + 'cef\User Data';
Everything works fine as long as paths conatin english letters, but cef is unable to start if path contains other languages symbols
Specifically, the following returns false at checking DLL version stage in uCEFApplicationCore.pas:
Code: Select all
if CheckDLLVersion(LibCefPath,
CEF_SUPPORTED_VERSION_MAJOR,
CEF_SUPPORTED_VERSION_MINOR,
CEF_SUPPORTED_VERSION_RELEASE,
CEF_SUPPORTED_VERSION_BUILD) then
I am sure my project has default lazarus/fpc unicode support enabled, and tried different workarounds such as converting my strings to utf16 or assigning constants to string type first, but nothing changed.

Hi,
Thanks for reporting this issue!
I'll take a look as soon as I can.

if I set
Code: Select all
GlobalCEFApp.CheckCEFFiles:=false;
then that error is skipped, but the following fails:
Code: Select all
{$IFDEF MSWINDOWS}
FLibHandle := LoadLibraryEx(PChar(LibCefPath), 0, LOAD_WITH_ALTERED_SEARCH_PATH);
{$ELSE}
FLibHandle := LoadLibrary(PChar(LibCefPath));
{$ENDIF}

Forgot to add, this problem also happens with demos to me.
If I just compile simplebrowser demo without changing it, it works.
Then if I rename simplebrowser folder to rus name and try to run the newly created simplebrowser.exe, I get "CEF binaries missing" with a list of all cef binaries that are present in distribution and are inside my folder now

Please download CEF4Delphi again.
I just uploaded a new version that should fix that issue with unicode characters.

Thank you very much for your work. I use older version of cef4delphi (80.0.3987.163) in my (non-commercial) app and it is already distributed. While it has internal updater, I would like to avoid users downloading 250mb of new cef binaries. Will this fix work if I jury-rig your latest commit to sources of cef4delphi version I use now?

Yes, it will work.
You will need to apply the code changes in this commit :
