count = p.pcos_get_number(doc, "length:fonts"); for (i=0; i < count; i++) { if (p.pcos_get_number(doc, "fonts[" + id + "]/vertical")) { /* font uses vertical writing mode */ vertical = true; } } > Prerotated glyphs for vertical text and punctuation are mapped to the corresponding unrotated Unicode character. Use the following document option to preserve prerotated characters: decompose={vertical=_none} > Text line detection for vertical text can often be improved with the following page option: layoutanalysis={forcelayoutanalysis=0} 6.3.4 CJK Decompositions: Narrow, wide, vertical, etc. Unicode and many legacy encodings support the notion of fullwidth and halfwidth characters (sometimes also called double-byte and single-byte characters). By default, TET applies the Unicode decompositions wide and narrow which replace fullwidth and halfwidth characters with the corresponding standard-width counterparts. In order to preserve the original fullwidth and halfwidth characters you can use the decompose document option and disable the respective decompositions: decompose={wide=_none narrow=_none} Similarly, the small, square, and vertical decompositions also affect CJK characters. Since all these decompositions (including wide and narrow) are enabled by default, the characters are converted to their normal counterparts. Disable the respective decompositions in order to preserve the original characters. The following document option disables all decompositions: decompose={none} Table 6.1 demonstrates the CJK decompositions along with examples. See Section 7.3.2, »Unicode Decomposition«, page 100, for more information on decompositions. 80 Chapter 6: Text Extraction
