French notations are ignored when entering data in a text field

I have all the settings configured properly, but I get the same problem. Some diacritic are ignored. (like circumflex accent for example).

For instance : é and è are typed properly by TC but all of these letters > ä â à ë ê ì  ò ö ô, are ignored.

EDIT : after some investigations, the issue occur with "Sys.Keys" function. If I use the property Text of my textbox ( object.Text = value) all the letters with diacritics work. But in the case of my webapp, I can't use this method. My textbox need a real input to work properly.

EDIT 2 : I found a workaround. If I use low level procedures and write : "B^atiment" instead of "Bâtiment" it works.

Here's an example,

I'm using TC v15.55.53.7 on Windows v10.0.19045 using the following,

Also, ensure your system font supports other characters.

Are you able to use object.Keys("[Alt0226]"). For example,

In the documentation, it does mention you can use X and D tags for circumflex characters - I couldn't get this to work though.

Use Character Map, to get the correct code.

its not working. If I use [D221]a it gave me a regular "a" without the circumflex.

EDIT : okay ! So I have three syntax possible (for the word Bâtiment) :

 - B^^atiment > works with Sys.Keys natively

 - B^atiment > my own solution

 - B[Alt+0226]timent > works with Sys.Keys too.
