I appear to have difficulties in viewing some fonts on Windows Font Viewer and on Nexus Font. Here's a side by side comparison of the Tulipan Rough Pro and Standard to illustrate the problem:
The Tulipan Rough Pro file is supposed to be an "original," but as you can see from the ss the numerals and a bit of punctuation are the only ones appearing correctly. I also tried to view it on myfontbook.com, looks the same there too. I don't know if my file is corrupted; it's only for this particular font file.
I was wondering why does this happen.
