Package: ttf-dejavu Version: 2.7-1 Tags: d-i, patch both nazli and dejavu provide Arabic / Farsi glyphs, but dejavu ones, being dejavu used as default font, are used. In order to use nazli for displaying Arabic / Farsi, such glyphs need to stripped out from ttf files. The attached patch strips such glyphs plus sets of other unused glyphs, making the udeb much smaller:
* unstripped * 440236 Jun 20 23:17 generated/DejaVuSans-Bold.ttf 406092 Jun 20 23:17 generated/DejaVuSans-Oblique.ttf 463320 Jun 20 23:17 generated/DejaVuSans.ttf * stripped * 180864 Jun 20 23:17 DejaVuSans-Bold.ttf 181644 Jun 20 23:17 DejaVuSans-Oblique.ttf 195320 Jun 20 23:17 DejaVuSans.ttf stripping was very much inspired from the way it's done for ttf-freefont package. regards, Davide PS: dejavu support for Arabic / Farsi is quite "young"; OTOH we ad positive feedback for nazli fonts.

+strip_glyphs.pe is a fontforge script (syntax is documented at
+http://fontforge.sourceforge.net/scripting.html)
+
+Usage: "strip_glyphs.pe in out glyphs"
+
+It strips glyphs out of a font file; glyphs can be ranges
+or single code points.
+Code points can be expressed as integers or in unicode notation (i.e
+"u215") and ranges are separated by ":".
+
+As a practical example, this commands were used to eliminate
+Arabic glyphs from the freefont package:
+
+./strip_glyphs.pe FreeSerif.ttf FreeSerif_strip.ttf u60c:u6d4 ufb50:ufefe
+./strip_glyphs.pe FreeSansBold.ttf FreeSansBold_strip.ttf u617:u633
+
+Note that "in" and "out" can be the same file; in that case, obviously,
+"in" gets overwritten.
