fixltx­hyph – Al­low hy­phen­ation of par­tially-em­pha­sised sub­strings

The pack­age fixes the prob­lem of TeX fail­ing to hy­phen­ate let­ter strings that seem (to TeX) to be words, but which are fol­lowed by an apos­tro­phe and then an em­pha­sis com­mand. The cause of the prob­lem is not the apos­tro­phe, but the font change in the mid­dle of the string.
The prob­lem arises in Cata­lan, French, Ital­ian and Ro­mansh.
