Medium Microsoft compilers and build tools expect some input files, such as the RSP file, to be encoded as UTF-8 with a Byte Order Mark (BOM). Currently, Bamboo generates RSP files for the MsBuild task encoded as UTF-8 without a BOM.
When the RSP file contains characters outside the basic ASCII set, such as those with diacritical marks (e.g., á, ã, ç, é, ñ, ü) and others from various Latin scripts, it is crucial to encode the file with a UTF-8 BOM to ensure accurate representation. Therefore, add a configuration option in the task UI to allow users to generate RSP files with UTF-8 BOM encoding for enhanced portability.
A failure message may appear in the logs such as:

Workaround
Use a Script task instead of the MsBuild task. The script should:
- Create the RSP file with the correct encoding, and then
- Call MSBuild, passing the resulting file as an argument.
Note: Ensure the correct code page is set for the shell in the script with the command:
chcp 65001
before creating the RSP file.
