[Bug 1008115] Re: man displays φ (u03C6) as ϕ (u03D5)
The problem appears in other characters too, e.g. in all the accented lowercase letters (άέήίόύώ) and possibly in more: Existing wrong encoding: Επιπλέον υλικό μπορεί να συμπεριληϕθεί στο παραγόμενο αποτέλεσμα Hexdump: ce 95 cf 80 ce b9 cf 80 ce bb e1 bd b3 ce bf ce 0010 bd 20 cf 85 ce bb ce b9 ce ba e1 bd b9 20 ce bc 0020 cf 80 ce bf cf 81 ce b5 e1 bd b7 20 ce bd ce b1 0030 20 cf 83 cf 85 ce bc cf 80 ce b5 cf 81 ce b9 ce 0040 bb ce b7 cf 95 ce b8 ce b5 e1 bd b7 20 cf 83 cf 0050 84 ce bf 20 cf 80 ce b1 cf 81 ce b1 ce b3 e1 bd 0060 b9 ce bc ce b5 ce bd ce bf 20 ce b1 cf 80 ce bf 0070 cf 84 e1 bd b3 ce bb ce b5 cf 83 ce bc ce b1 0a Correct encoding: Επιπλέον υλικό μπορεί να συμπεριληφθεί στο παραγόμενο αποτέλεσμα Hexdump: ce 95 cf 80 ce b9 cf 80 ce bb ce ad ce bf ce bd 0010 20 cf 85 ce bb ce b9 ce ba cf 8c 20 ce bc cf 80 0020 ce bf cf 81 ce b5 ce af 20 ce bd ce b1 20 cf 83 0030 cf 85 ce bc cf 80 ce b5 cf 81 ce b9 ce bb ce b7 0040 cf 86 ce b8 ce b5 ce af 20 cf 83 cf 84 ce bf 20 0050 cf 80 ce b1 cf 81 ce b1 ce b3 cf 8c ce bc ce b5 0060 ce bd ce bf 20 ce b1 cf 80 ce bf cf 84 ce ad ce 0070 bb ce b5 cf 83 ce bc ce b1 0a I'll try to make a list of all the problematic characters in a couple of days. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1008115 Title: man displays φ (u03C6) as ϕ (u03D5) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/groff/+bug/1008115/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Although this may be fixed in the upstream project's revision control system it is not actually Fix Committed for the Ubuntu package of that software.

[Bug 1008115] Re: man displays φ (u03C6) as ϕ (u03D5)
The problem was not related to PS output, it was a mapping bug from Unicode character codes to groff entities. This is fixed now in the CVS.

[Bug 1008115] Re: man displays φ (u03C6) as ϕ (u03D5)
groff_char(7) seems to document some oddities around phi: These glyphs are intended for technical use, not for real Greek; normally, the uppercase letters have upright shape, and the lowercase ones are slanted. There is a problem with the mapping of letter phi to Unicode. Prior to Unicode version 3.0, the difference between U+03C6, GREEK SMALL LETTER PHI, and U+03D5, GREEK PHI SYMBOL, was not clearly described; only the glyph shapes in the Unicode book could be used as a reference. Starting with Unicode 3.0, the reference glyphs have been exchanged and described verbally also: In mathematical context, U+03D5 is the stroked variant and U+03C6 the curly glyph. Unfortunately, most font vendors didn't update their fonts to this (incompatible) change in Unicode. At the time of this writing (January 2006), it is not clear yet whether the Adobe Glyph Names `phi' and `phi1' also change its meaning if used for mathematics, thus compatibility problems are likely to happen – being conservative, groff currently assumes that `phi' in a PostScript symbol font is the stroked version. In groff, symbol `\[*f]' always denotes the stroked version of phi, and `\[+f]' the curly variant. It might be useful if somebody familiar with Greek could take this up directly with groff upstream, since it seems that the needs of mathematical Greek may conflict with those of real Greek? It certainly seems odd that the definitions in glyphuni.cpp and uniglyph.cpp aren't mirror images of each other. ** Package changed: man-db (Ubuntu) = groff (Ubuntu) ** Changed in: groff (Ubuntu) Importance: Undecided = Medium ** Changed in: groff (Ubuntu) Status: New = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1008115 Title: man displays φ (u03C6) as ϕ (u03D5) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/groff/+bug/1008115/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1008115] Re: man displays φ (u03C6) as ϕ (u03D5)
being conservative, groff currently assumes that `phi' in a PostScript symbol font is the stroked version. Ouch, yeah if there are printers out there with embedded fonts that follow Unicode 3.0, that's a good point. But on the other hand it breaks Greek man pages. Since that was written in 2006 though, they may now decide to switch the default to Unicode = 3.0, or at least to introduce some option to select the targeted Unicode version. Thank you Colin, I'll take it up directly with groff upstream (after a couple of weeks) and update this bug report accordingly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1008115 Title: man displays φ (u03C6) as ϕ (u03D5) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/groff/+bug/1008115/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
