Index with accented characters with Microsoft HTML Help output

[claudeb41321034]

When I create an index with a key containing accented characters, they disappear in the index for Microsoft HTML Help output (e.g. "First" => "First").
To reproduce :

1. Create a new project with 1 topic
2. Create a key containing an accented character (e.g. First) in the index pointing to the topic
3. Choose the Microsoft HTML Help output
4. Generate output
5. Browse the help index and see that "First" becomes "First".

I have also set the output language and the topic language to French but it doesn't change anything.

Bit of a guess here. Is your operating system also French? I wonder if it's the same underlying problem as described in Item 11 at Snippets (grainge.org)

Beyond that, I don't know the cause.

My system is indeed in French.
I followed the recommendations described on item 11 at Sippets (diagnostics and reinstall Microsoft Help Compiler) but it doesn't work any better
In my previous post you have to read (ex: "Première" => "Premire")

I tried with RH2019 New UI without changing windows settings, project settings or file settings, and "Première" appears in the chm index correctly.

I also tried on a different computer with RH2020 and the accented character is deleted, even when I change all of the settings. So to me it seems to be a problem with RH2020.

See the following page for support contact options. The email address is recommended as it goes to dedicated RH people.
