The following also applies to your Charis SIL font.
First I renamed the files to use the Regular, Bold, Italic, and BoldItalic suffixes that the Kobo seems to use.
The main problem with both Modified and Modified Larger is getting Kobo firmware post 2.1.5 to display italics, and I have had very inconsistent results. At first Charis Modified seemed to be OK if I used the default US locale, but not if I changed the locale to UK (https://www.mobileread.com/forums/sho...d.php?t=206200
). Since I have added on Modified Larger I can't get either font to display italics, regardless of the locale (I am cold rebooting after changing locale). That is, I can't get italics to display with your Charis fonts even on the default US locale.
I have also raised this problem with Kobo support; they requested a sample epub that displays this problem, which I sent to them, and it has gone to second tier support. Fingers crossed this will be fixed in the next firmware release.
Not sure if this is your issue but I tried the ModifiedLarger variant and it did work for me.
Basically, I had to rename the four files to include the spaces in the font family name and came up with the following (I used Fontforge to see the font family name.)
Charis SIL ModifiedLarger-Regular.ttf
Charis SIL ModifiedLarger-Bold.ttf
Charis SIL ModifiedLarger-BoldItalic.ttf
Charis SIL ModifiedLarger-Italic.ttf
After copying the renamed files to the Kobo fonts directory, disconnecting from the computer and power cycling the Kobo, the ModifiedLarger font worked.
Edit: I tried switching to several English locales, French Canada, Spanish and Japanese and I saw no issues with displaying text style/weight other than oblique not working which it never does.
