Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
When upgrading a custom module to Odoo 19, I get the following error is odoo log:
ValueError: Unicode strings with encoding declaration are not supported. Please use bytes input or XML fragments without declaration.
I have removed the following line from the beginning of the XML files, but still have the same error:
<?xml version="1.0" encoding="utf-8" ?>
Note: I am upgrading from v15 to v19.
What is the fix to such error message?
Hi,
To fix this, ensure that all XML files start directly with <odoo> or <record> and do not include the line <?xml version="1.0" encoding="utf-8"?>. You should also check for invisible BOM characters, which are often added by text editors. Re-save the files using UTF-8 encoding without BOM, preferably in a clean editor like VS Code.
Finally, verify that all XML files listed in the module manifest (__manifest__.py) are properly encoded and do not contain unwanted characters or spaces before the <odoo> tag. Once all files are saved as UTF-8 without BOM, the error will be resolved.
Hope it helps
Hello,
<?xml version="1.0" encoding="utf-8" ?>
I found the space near question mark inside the tag.
Please try below:
<?xml version="1.0" encoding="utf-8"?>
Not only did OP state he has removed that line, it's also not invalid XML either way.
