No, I am not.  But how it could if I did mess with ‘fontset-default’?  Anyway, let us consider that example:

| Unicode charset: “Eĥoŝanĝo ĉiuĵaŭde”, “Γειά σας”, “שלום”, “Здравствуйте!”

Before (note that the fallback font is inconsistent even linewise — the first opening quote is different from others):

[93.png (image/png, inline)]

[Message part 3 (text/plain, inline)]

After:

[94.png (image/png, inline)]

[Message part 5 (text/plain, inline)]

It looks like the way it should be — first try the current fonset, only then fallback to ‘fontset-default’.

Do you mean that you could not reproduce this?

I’ve installed the lastest upstream version of Terminus [0] — and got the same issue.  So it does not seem to be Debian-specific.
