Arbortext Editor 7.1 - File encoding changes from Windows-1252 to UTF-8 after saving SGML files

Hello,

We are experiencing unexpected behavior with Arbortext Editor 7.1 regarding the encoding of SGML files.

Issue description:

1. We open an existing SGML file in Arbortext Editor.
2. The file encoding is ANSI Windows-1252 (verified using Notepad++).
3. After opening the file in Arbortext Editor and saving it (even without any content changes), the file encoding is automatically changed.
4. The saved file is now encoded in UTF-8 (verified using Notepad++).

Question:

Is there a parameter or configuration setting in Arbortext Editor 7.1 that defines the default encoding used when saving SGML files?

Our expectation is that the original encoding (Windows-1252) should be preserved when saving an existing file, unless an explicit conversion to UTF-8 is requested.

We have reviewed the Arbortext preferences but could not find any setting that controls the default encoding used during file saving.

Could you please advise on:

- whether there is a preference or configuration parameter to control the save encoding;
- whether it is possible to force Arbortext Editor to preserve the original file encoding when saving SGML documents;
- whether an ACL customization (for example, through `init.acl` or another configuration file) is required to enforce a specific encoding.

Environment information:

- Product: Arbortext Editor
- Version: 7.1
- Document type: SGML
- Original encoding: Windows-1252 (ANSI)
- Encoding after saving: UTF-8

Thank you in advance for your assistance.

Best regards,
