Text Formatting ⇒ Dysfunctionnal justification

[PierreJ]

Hello All,

In my last text, justification is dysfunctional: I've had to use about 200 \linebreak commands, sometimes 2-3 in one paragraph, whereas I didn't need any in my previous texts (I didn't even know about \linebreak before). Why is this the case? Thanks in advance for your help.

Here is a MWE with actual text in attached file to show the problem.

Cette façon ironique d'implanter la ségrégation enrageait les racistes américains, ce qui réjouissait d'autant plus les patrons des pubs concernés.

I cannot test it, because you have not marked the code as code (simply select the code with the mouse and click the »Code« button in the toolbar) and it is not a minimal working example, because it does not show the problem but only a not working snippet. However I would expect that these are overfull \hboxes. In this case there should be several warnings in the log file. To get less such overfull \hboxes you can remove your changes of \righthyphenmin and \lefthyphenmin to allow some more hyphenation. You can also try package microtype.

[PierreJ]

Thank you very much for your explanation! I've corrected my post.

The problem with changing \righthyphenmin and \lefthyphenmin is that I then get faulty hyphenation cases (for instance, in French, it's forbidden to have "chan-gent").

[PierreJ]

I've just found a solution: replacing \usepackage{ebgaramond} with \usepackage{libertinus} solves almost all cases of lengthened lines.
The last remaining ones were solved with the line \usepackage[protrusion=true,expansion=true,final,babel]{microtype}. Thanks a lot MJK !

babel sets \lefthyphenmin to 2 and \righthyphenmin to 3 for french which AFAIK is correct for French (if it isn't, you should make a bug report). But if only some words are faulty hyphenated, you should correct these words, e.g., using \hyphenation{changent} in your document preamble. Global settings of \lefthyphenmin and \righthyphenmin to large values make hyphenation and therefore paragraph breaking difficult to TeX. So it is not recommended to do so to solve hyphenations problems of some words only.

BTW: AFAIK

used only allowed hyphenations. So there is also no need to change the font. However, of you like Linux Libertine more than Garamond, just use it. (But don't expect, that this solves all hyphenation problems for every text and for all time).

Moreover, if you are using the current French hyphenation pattern, changent will not be hyphenated with the default settings:

in the log-file. So there are not any hyphenation points in «changent». If you get another result, you should check, if the hyphenation patterns for french are installed and activated and if your TeX installation is up-to-date.

Ijon Tichy, thank you very much for your input. I'll follow your advice and use \hyphenation to solve special cases. I'm not sure it's a bug problem, maybe it's just too complicated to manage. For instance, "pa-rent" is legal if it means "relative" but it's illegal if it means "(they) avert".

Funnily, changing fonts did solve most of my hyphenation problems (please see the attached picture, to be compared with the picture attached to my first post). The last issues (line 6 and 18) were solved by the microtype package.
