...there are certain fonts that only have a single style. For example if you use the font with the name Myfont in an svg file created by Adobe Illustrator, you will get an svg file that contains Myfont-Regular as font name. Inkscape cannot handle this font name as it awaits only the font name Myfont. My proposal is that if Inkscape cannot find the font Myfont-Regular, it should automatically look for the font Myfont-Regular when opening an svg file.

Migrator's Notes:

• A quick test...
  • SVG from AI CS5*, text with CRs: text_block.zip
  • SVG from AI CS5*, flowed text: text_flowed.zip
  • Chivo font family: https://www.omnibus-type.com/fonts/chivo/
• The onus is possibly (probably?) on Adobe Illustrator not creating spec-perfect SVG. But go and argue with the 800-lb gorilla.

*The only version I had access to. Caveat: it produces SVG 1.1. Hopefully this doesn't render these tests useless.
