That's because Emacs has no idea that you are using SPUA planes for Polish. You need to tell Emacs about that by augmenting your fontset. (And even after you do that, there could be problems, because Emacs doesn't treat PUA ranges of Unicode codepoints as characters.)

The PUA from the Basic Multulingual Plane are used by me for years and do not require doing anything with the fontset. For example, LATIN SMALL LETTER LONG S WITH FLOURISH (coming from the Medieval Unicode Font Initiative) is displayed without problem and the appropriate font is found automatically: character: =EE=A2=B7 (displayed as =EE=A2=B7) (codepoint 59575,= #o164267, #xe8b7) xft:-psbk-Junicode-normal-normal-normal-*-15-*-*-*-*-0-iso10646-1 (#x94= C) The same should happen for the characters from plains 15 and 16. However now even the explicit selection of the appropriate font doesn't help. > (And even after you do that, there could be problems, because Emacs > doesn't treat PUA ranges of Unicode codepoints as characters.) Really? What do you exactly mean? My experience contradicts this statement. I think the Emacs code just for some reason limits the range of the Unicode characters, and the limitation should be removed. Regards Janusz --=20 ,=20=20=20 Janusz S.

Of course, my expertise in this part of Emacs is rather limited, so I might be missing something. Corrections with explanations are welcome. > > (And even after you do that, there could be problems, because Emacs > > doesn't treat PUA ranges of Unicode codepoints as characters.) > > Really? What do you exactly mean? My experience contradicts this > statement. Please look at the various settings of character-related databases in Emacs: they basically deny PUA codepoints any reasonable character properties. IOW, Emacs doesn't know anything about these codepoints, in terms of the character attributes and properties it needs for proper support. Font selection is just the tip of the iceberg. The feature we miss is some facility to tell Emacs the semantics of a range of PUA codepoints, so that the rest of the code will support them properly and correctly. > I think the Emacs code just for some reason limits the range of the > Unicode characters, and the limitation should be removed. Any evidence that such a limitation exists and/or where does it happen?

I meant evidence that the root cause of this is some limitation on the range of Unicode characters. There's no dispute about the facts, but I'm not aware of any limitation of the kind that you suggested. Also, please describe in detail how you selected the font in question.

You are right, perhaps I jumped to a wrong conclusion, but it seemed to me the simplest explanatation. Perhaps my bug report (I still think it is a bug) should be renamed to "Emacs doesn't find font for some characters". > Also, please describe in detail how you selected the font in question. > I don't think you told that in your original report. I didn't told because I expected the font to be found automatically. In an additional experiment I just used `S-down-mouse-1=E2=80=99 and select= ed the font from the list.

I don't know how vim selects the fonts, but I'm sure it's very different from what Emacs does. We need to understand what prevents Emacs from using this font as you expected. Anyway, I think it's time to present more details, if you please: . does this happen in "emacs -Q"? . did you customize your fontsets, and if so, can you show those customizations? . which codepoints are used for the problematic characters, and which characters are those? do they have codepoints in Unicode? . can you make the font in question available for download, so we could try debugging this in Emacs? . assuming the font is installed, can you show a minimal recipe for reproducing the problem in "emacs -Q"?

An appropriate font is understand preparation, but not yet available publicty. When the font was installed in ./loca/share/fonts, a QT program found it and displayed the characters correctly. Emacs, to the contrary, for character: =F3=B0=80=80 (displayed as =F3=B0=80=80) (codepoint 983040, #o36= 00000, #xf0000) reports "no font available".
