invalid PostScript font name

[sunaku]

Hello,

I tried using bdf2ttf to transform the Tamzen font into TTF, but when I double-click on the resulting TTF file under Windows 7, an error dialog appears saying "Windows Font Viewer: The requested file ... is not a valid font file.". Similarly, I'm getting an error message when opening the resulting TTF file in FontForge under Linux: 😞

In the above screenshot, that "|0003|" Unicode glyph at the end of the font name is suspicious.

Steps to reproduce the bug

$ mkdir -p ~/.fonts/tamzen-font

$ git clone https://github.com/sunaku/tamzen-font ~/.fonts/tamzen-font

$ cd ~/.fonts/tamzen-font

$ git checkout bdf2ttf

$ cat ttf/TamzenForPowerline.ini
Fontname = TamzenForPowerline
Version = 1.11.5
Copyright = Copyright
Trademark = Trademark

$ bdf2ttf ttf/TamzenForPowerline-regular.ttf ttf/TamzenForPowerline.ini bdf/TamzenForPowerline*r.bdf
Input files:
  bdf/TamzenForPowerline5x9r.bdf
  bdf/TamzenForPowerline6x12r.bdf
  bdf/TamzenForPowerline7x13r.bdf
  bdf/TamzenForPowerline7x14r.bdf
  bdf/TamzenForPowerline8x15r.bdf
  bdf/TamzenForPowerline8x16r.bdf
  bdf/TamzenForPowerline10x20r.bdf

$ bdf2ttf -b ttf/TamzenForPowerline-bold.ttf ttf/TamzenForPowerline.ini bdf/TamzenForPowerline*b.bdf
Input files:
  bdf/TamzenForPowerline5x9b.bdf
  bdf/TamzenForPowerline6x12b.bdf
  bdf/TamzenForPowerline7x13b.bdf
  bdf/TamzenForPowerline7x14b.bdf
  bdf/TamzenForPowerline8x15b.bdf
  bdf/TamzenForPowerline8x16b.bdf
  bdf/TamzenForPowerline10x20b.bdf

$ fontforge ttf/TamzenForPowerline-regular.ttf
... now observe the error shown in the screenshot above ...

Thanks for your consideration. 😅

I can't reproduce your problem, but get font files attached. Please check this.
TamzenForPowerline.zip
It seems correct font files for me.

I have compiled bdf2ttf by MSVC10's 32bit compiler on WIndows 10,
converted and checked result TTF files on same machine.

Thanks! 👍 Your generated fonts worked successfully in Linux FontForge and Windows 7. 💯

I should have mentioned that I compiled and ran bdf2ttf under Linux, using make gcc target.
So there appears to be some functional difference between the results of MSVC and GCC. 🐛

There seems be bad assumption of bdf2ttf.

bdf2ttf consider unsigned long is 32bit. But most of gcc treat it as 64bit.
It will cause some problems.

[koron]

It would be better that use size aware types uint32_t or so.
But I don't have time to do that.

[koron]

I have fixed for gcc.

@sunaku please try again with recent version.

[sunaku]

Thanks @koron! 🙇 I tried the fix but the problem still occurs. 😞 I will try to debug it further. 👷

[sunaku]

I tried rebuilding bdf2ttf for 32-bit architecture (my system is 64-bit):

$ make gcc CFLAGS=-m32 LDFLAGS=-m32
make -f compile/Make_gcc.mak
make[1]: Entering directory '/home/sunny/lab/bdf2ttf'

make[1]: Leaving directory '/home/sunny/lab/bdf2ttf'

I still get the "Postscript font name" error in FontForge 😞 but at least the embedded bitmap fonts appear correctly now 😌 (previously FontForge rendered them as empty, red boxes). 👷 Next idea...

[koron]

I still get the "Postscript font name" error in FontForge

I won'f fix about this.
Because it is not in bdf2ttf's scope.
But welcome to receive patches.

[sunaku]

😅 Fair enough, thanks for your help! 🙇
