Formatting CJK text. The textflow engine is prepared to deal with CJK text, and properly
treats CJK characters as ideographic glyphs as per the Unicode standard. As a result,
CJK text will never be hyphenated. For improved formatting the following options are
recommended when using Textflow with CJK text; they will disable hyphenation for inserted
Latin text and create evenly spaced text output:
hyphenchar=none
alignment=justify
shrinklimit=100%
spreadlimit=100%
Vertical writing mode is not supported in Textflow.
Justified text in a narrow fitbox. The narrower the fitbox, the more important are the
options for controlling justified text. Figure 8.23 demonstrates the results of the various
methods for justifying text in a narrow fitbox. The option settings in Figure 8.23 are basically
okay, with the exception of maxspacing which provides a rather large distance between
words. However, it is recommended to keep this for narrow fitboxes since otherwise
the ugly forced hyphenation caused by the split method will occur more often.
If the fitbox is so narrow that occasionally forced hyphenations occur, you should
consider inserting soft hyphens, or modify the options which control justified text.
Option shrinklimit for justified text. The most visually pleasing solution is to reduce
the shrinklimit option which specifies a lower limit for the shrinking factor applied by
the shrink method. Figure 8.24a shows how to avoid forced hyphenation by compressing
text down to shrinklimit=50%.
