I make heavy use of diacritics for roman transliterated text from Sanskrit. This makes use of certain special characters. However, as you can see in the image attached, OnlyOffice appears to use fallback fonts for these instead of the MS fonts like Times New Roman. I am sure that Times has these characters since I used it back when I was on Windows running Word.
Could you please look into this issue? I am on CachyOs.
Thanks! Aside from this OnlyOffice has been wonderful and has made my switch to Linux more smooth.
