Make the delivery copy
- Save a copy that keeps the original editable text.
- In Inkscape, select the text and use Path → Object to Path. Use the equivalent outline conversion in your editor.
- Save a separate SVG and inspect its letters and enclosed counters.
Check what changed
The SVG checker reports live text elements. Zero text elements means the file has no live SVG text; it does not prove that all letters are correct or joined for a stencil.
