Because of a question on tex.sx I tried to use the source han sans fonts. I installed (in windows 10) the fonts from this zip-file: https://github.com/adobe-fonts/source-han-sans/blob/release/OTF/SourceHanSan... Trying to use them with latex/luaotfload failed with a memory exhausted error while trying to write the lua-file. In context \starttext \font\test={name:sourcehansans} \test abc \stoptext gave the error: fonts > otf loading > loading 'c:/windows/fonts/SourceHanSans-Regular.otf', hash 'sourcehansans-regular' otf reader > loading of table 'vorg' skipped otf reader > invalid index in single format 1: 65353 -> 67212 (max 65535) otf reader > rule 1 in gsub lookup 's_s_5' has empty lookups fonts > otf loading > loading failed due to read error fonts > defining > forced type 'otf' of 'c:/windows/fonts/SourceHanSans-Regular' not found fonts > defining > font with asked name 'c:/windows/fonts/SourceHanSans-Regular' is not found using lookup 'name' fonts > defining > unknown font 'c:/windows/fonts/SourceHanSans-Regular', loading aborted xelatex had no problems to use the font. Is this an error in the font or in the fontloader? -- Ulrike Fischer http://www.troubleshooting-tex.de/
