Show which characters a font can't render

Published May 5, 2026

Sign Customiser now tells customers exactly which characters in their text the chosen font can’t render, instead of a generic “invalid characters” warning. The same check has been extended across every sign type and runs again at add-to-cart, so orders with unrenderable text can no longer slip through to the merchant.

What’s Changed

  • Specific character feedbackThe “invalid characters” message now lists the exact glyphs the font is missing, so customers know whether to fix a typo, swap a symbol, or pick a different font
  • Coverage across all sign typesFont glyph validation previously only ran for material-length pricing; it now runs for every sign that uses customer-typed text
  • Add-to-cart safety netIf an unsupported character slips past the live warning, the customiser now blocks add-to-cart and surfaces the same specific message, preventing unrenderable orders from reaching the merchant
  • Updated default labelThe default invalid-characters label includes a {characters} placeholder so merchants who customise the wording still see the offending characters listed in their own copy
