UNICODE characters not appearing in left panel in CHM file

But in the left panel I am getting ???? marks

Ensure to set the correct language in your project

The HTML Help (CHM) Viewer in Windows is NOT fully Unicode and in some cases it depends on language/code page settings which you can setup in project options.

Please ensure that you have set the correct language for your project:

1. On the Project tab, click Project Options.
2. In the left side, select the HTML Help section.
3. In the right side, check (or change) the language specified for your help project.
4. Click OK.

HTML Help and Unsupported Languages

When you create a .CHM help file, HelpSmith converts Unicode texts used in the Table of Contents, Index, full-text search etc. to an ANSI/double-byte encoding. This is because the HTML Help (CHM) format does not natively support Unicode in its own Windows.

While Windows provides codepages for most languages which make that conversion possible, there is a list of languages for which codepages are not available. In these cases, it is not possible to create a CHM file for those languages.

Remark: Please note that this restriction is related to the Windows and HTML Help (CHM) format, but not to HelpSmith, which is a Unicode application.

Using Web Help format instead of .CHM help file

As a solution, you could consider using the Web Help format instead of HTML Help (CHM). A web help system can be integrated with a web-based or desktop application, as explained here.

Additionally, since HelpSmith ver. 10.1.1 a Web Help system can be used both on a web server and on a local computer without a server.
