What’s new in babel 3.57

2021-04-07

Transforms added to ini files

Arabic ▸ transliteration.dad ▸ Applies the transliteration system devised by Yannis Haralambous for dad. Not yet complete, but sufficient for many texts.

Croatian ▸ digraphs.ligatures ▸ Ligatures DŽ, Dž, dž, LJ, Lj, lj, NJ, Nj, nj. It assumes they exist. This is not the recommended way to make these transformations (the best way is with OTF features), but it can get you out of a hurry.

Greek ▸ diaeresis.hyphen ▸ Removes the diaeresis above iota and upsilon if hyphenated just before. It works with the three variants.

Hindi ▸ transliteration.hk ▸ The Harvard-Kyoto system to romanize Devanagari.

Hungarian ▸ digraphs.hyphen ▸ Hyphenates the long digraphs ccs, ddz, ggy, lly, nny, ssz, tty and zzs as cs-cs, dz-dz, etc.

Uyghur hyphenation (lua)

Some tentative code has been added to the Uyghur locale for the words to be hyphenated correctly, preserving the joining forms. See CSS Text Module Level 3 – Shaping Across Intra-word Breaks. It assumes the basic forms (initial, medial, final).

Here is an example (text copypasted from Syllabification-for-Uyghur.

[Update. At the time of this writing (2021) there was some work in progress for a set of Uyghur hyphenation rules. Sadly, as of 2023 this project seems abandoned.]

Other changes

• Transforms: {xxxx} syntax also in string =, which is replaced by the character with the given hex code (at least 4 ‘hex digits’).

• magyar as alternative name to hungarian in \babelprovide. [Update. But the preferred name is still hungarian, per the Unicode CLDR.]
