From 562f34819229080abb05b4e7ae7e9e47fc84c6eb Mon Sep 17 00:00:00 2001 From: suzuki toshiya Date: Sat, 20 May 2023 12:52:25 +0000 Subject: [PATCH] [doc] Type1 GX (sfnt-wrapped Type1) is not supported. * docs/formats.txt: Clarify the reference of Type1 GX, and state that this format is not supported. This is because the content `TYP1' table is not exactly same with the Type1 font format specification; no eexec encryption is used.
