Problems loading some fonts (e.g. Google fonts) #2

Hi!
a rewrite of the Tcl files into Python seems appropriate to make the package more maintainable.
In tukaan I use the
extrafontpackage, and there I rewrote the Tcl files into Python, which actually wasn't a big deal, and made the package indeed much more maintainable.I experimented a bit with Google fonts and found the problem with their name info. Actually this problem seems to be Unix-specific, though I haven't tried if Google fonts work on Windows with it.
Normal font files contain name records inlatin-1(for *nix) andUTF 16 BigEndian(for Windows). The problem is that these Google fonts store the records in the name table only in utf16be, howeverextrafontreads records encoded in utf16be only under Windows.

So if you remove the triplet and platform checking stuff fromfontnameinfo.tcl, it works just fine with Google fonts too.Hey!
That is super cool, thank you for letting me know you looked into this! If you are okay with it, I might at some point back-port your changes to this repository, for the sake of the
tkextrafontpackage.For now I am regularly looking at your progress on
tukaan, which is a much more radical approach to what I tried to accomplish with TkinterEP, but it looks really promising. Unfortunately I have very little time for hobby-programming at the moment, but I am eager to see what you create.Reacted by Benedek Dévényi and HarshilReacted by Harshil
Loading some fonts, in this case tested with the Google fonts
RobotoandNoto Sans, is not possible with the package. This is due to problems in thefontnameinfo.tclfile, which is unable to parse the required information from the font files.Additional complications arise with these fonts as they are split into multiple separate files. Loading the fonts with
extrafont::core::loadworks just fine, but only one weight can be loaded at the same time. This can be avoided by merging the different files into a single file usingfonttools.If
fonttoolsis already added as a dependency to make the package work with many different fonts, a rewrite of theTclfiles into Python seems appropriate to make the package more maintainable.
