ApplyIndicReorder

Signatuur

function ApplyIndicReorder(const Wide: UnicodeString): UnicodeString;

Doel

Stuurt Indic-tekst naar de geregistreerde herschikkingshelper per script. De functie scant Wide, segmenteert scriptbereiken, houdt niet-Indic-tekst byte-stabiel en bereidt voor op cmap en GSUB

  • Sinhala (sinh, U+0D80-U+0DFF) - R1-R5 with Sinhala pre-base and split-matra handling
