Thanks for following up to clarify! From taking a second look I believe I see the issue; when the Archivo Narrow font is installed from Google Fonts on Windows 7, the font family in the dropdown is “Archivo” and the variations can be selected in the next dropdown; however, when the same font is installed on Windows 10, it seems to break up into “Archivo Narrow Bold”, “Archivo Narrow Bold Italic”, etc… rather than just “Archivo”, and this is causing the font to not render correctly with your existing web fonts. This also seems to be causing issues even when using the CSS link that Google Fonts provides, despite font mapping.
This seems like a bug to me that the font changes between Windows 7 and Windows 10 and won’t render correctly, so I’ll go ahead and file it on our end for further investigation. We’ll follow up here with any updates, but in the meantime we’d recommend keeping an eye on the Axure RP 8 bug fix thread for updates.
For now as a workaround, there are a couple of options that appear to work. For one, setting the font to something you’re not using (such as Arial) and mapping different weights of that font (Bold, Regular, etc…) to your web font seems to work.
Of course, the caveat is that the font doesn’t look correct on the canvas while editing. Another possibility is to convert the fonts to images by right-clicking them and choosing “Convert to Image”, which will prevent them from changing in the browser but will also prevent them from being edited.
Hopefully one of those helps a bit while the investigation is underway!
