Different historical sources sometimes use non-standard forms, while modern converters normally follow conventional notation rules.

Useful conversion workflows

  • Create educational examples.

What to verify

  • Use standard subtractive notation where expected.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
