LaTeX bugs database

This search tool allows you to search the LaTeX3 project team's database of all bug reports for LaTeX. If you discover what you believe to be a bug with LaTeX, you can search this database to find out if it has already been reported.

Note that you can only search for bugs which were reported after December 1994, when we made the database public.

Description of bug:
The problem was reported by stefano on
http://tex.stackexchange.com/questions/121842/polutoniko-greek-in-texlive-2013.

The greek.ldf 2013/05/17 v1.4 contains 8-bit characters that break with
Unicode TeX engines. The test file comes from Enrico Gregorio:
http://tex.stackexchange.com/a/112939/16967

Using ^^-notation will might fix the issue.

μῆνιν ἄειδε θεὰ Πηληϊάδεω Ἀχιλῆος
οὐλομένην, ἣ μυρί᾽ Ἀχαιοῖς ἄλγε᾽ ἔθηκε,
πολλὰς δ᾽ ἰφθίμους ψυχὰς Ἄϊδι προΐαψεν
ἡρώων, αὐτοὺς δὲ ἑλώρια τεῦχε κύνεσσιν
οἰωνοῖσί τε πᾶσι, Διὸς δ᾽ ἐτελείετο βουλή,
ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε
Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς.
τίς τ᾽ ἄρ σφωε θεῶν ἔριδι ξυνέηκε μάχεσθαι;
ητοῦς καὶ Διὸς υἱός: ὃ γὰρ βασιλῆϊ χολωθεὶς
νοῦσον ἀνὰ στρατὸν ὄρσε κακήν, ὀλέκοντο δὲ λαοί,
οὕνεκα τὸν Χρύσην ἠτίμασεν ἀρητῆρα
Ἀτρεΐδης: ὃ γὰρ ἦλθε θοὰς ἐπὶ νῆας Ἀχαιῶν
λυσόμενός τε θύγατρα φέρων τ᾽ ἀπερείσι᾽ ἄποινα,
στέμματ᾽ ἔχων ἐν χερσὶν ἑκηβόλου Ἀπόλλωνος
χρυσέῳ ἀνὰ σκήπτρῳ, καὶ λίσσετο πάντας Ἀχαιούς,
Ἀτρεΐδα δὲ μάλιστα δύω, κοσμήτορε λαῶν:
Ἀτρεΐδαι τε καὶ ἄλλοι ἐϋκνήμιδες Ἀχαιοί,
ὑμῖν μὲν θεοὶ δοῖεν Ὀλύμπια δώματ᾽ ἔχοντες
ἐκπέρσαι Πριάμοιο πόλιν, εὖ δ᾽ οἴκαδ᾽ ἱκέσθαι:
παῖδα δ᾽ ἐμοὶ λύσαιτε φίλην, τὰ δ᾽ ἄποινα δέχεσθαι,
ἁζόμενοι Διὸς υἱὸν ἑκηβόλον Ἀπόλλωνα.

Thank you for your report, Heiko. Please, contact Günter Milde,
who is the current maintainer of the Greek style (I'm cc'ing
this message to him.)

Cheers
Javier

PS. Günter, please find the report here:

http://www.latex-project.org/cgi-bin/ltxbugs2html?category=Babel&responsible=anyone&state=not+closed&keyword=&pr=&search=

You may also want to see other bugs related to the Greek style.

Thanks for the report. The bug was also reported from other side in a
private mail and is fixed in version 1.5a which I uploaded to CTAN
on 2013-06-27. However, the fix is not (yet) visible - CTAN still has
greek.dtx version 1.5.

Guenter,

Thanks. And I'll update the LaTeX bug tracker in a few hours
(somewhat busy right now).

Cheers
