The counter Latine commands, "latinpar", "\LT" and "\setlatin". To enable mirroring of BiDi mirrored characters, like () and. This also enables "implicit bidi", so that you don't need to explicitly specify the direction of individual Arabic sentences inside Latin context in vise versa. (Example by Rik Kabel on the mailing list, )ĭepending on the font, correct niqqud placement requires some combination (sometimes all) of the following font features: lang, ccmp, and script. The same settings work well for Narkisim.
There is a font feature hebrew already predefined For David_CLM you only need the script setting. (To compare this to a non-normalized version of the same text, copy and paste the text of Genesis 1:1 from it cannot be included in the example above because, alas, the Wiki would apply Unicode normalization to it!) ] %Set up the main font: \definefontfamily \setupbodyfont %Set up right-to-left alignment: \setupalign \starttext %Normalized Unicode mark order: %Setup minimal font features: \definefontfeature \definefontfeature \definefontfeature \definefontfeature \definefontfeature \definefontfeature Liga =yes,dlig =yes,rlig =yes,clig =yes,calt =yes ] \definefontfeature [mode =node,analyze =yes,language =dflt,ccmp =yes, \definefontfeature [mode =node,analyze =yes,language =dflt,ccmp =yes,Īutoscript =position,autolanguage =position, If you have to set a language depends on the font (often dflt is ok).
When a minimal set of OpenType features needed to render Hebrew points correctly is employed, this normalized sample text will fail to typeset several points. But if you copy and paste the un-normalized text from the link above into the same example, you will find that it gets typeset completely and correctly.
This is because most Hebrew fonts anticipate a particular ordering of certain classes of characters in their substitution tables, and Unicode normalization reverses this ordering in some cases. This happens most often when the shin dot and sin dot (which Unicode assigns to the combining classes 24 and 25) and / or dagesh (which Unicode places in combining class 21) co-occur with vowels (which are variously assigned combining classes between 10 and 20) the fonts expect the shin / sin dot to occur first, then the dagesh, then the vowel, but Unicode normalization sorts these characters in the opposite order.
