Thank you so much for spending your precious time on helping me!
About my second issue:
I found that there are 5 invalid font files in the folder with similar issues. Besides these 5 files, there are some other font files in the folder that contain information on their properties but cannot be opened and installed.
But my concern is about these 5 invalid font files because there’s no information required by SIL OFL 1.1 in their properties.
I’ve prepared the 5 invalid font files and the 5 valid font files with the same name, and their copyright notice and license full text.
Here’s the link to download the zip file: https://drive.google.com/file/d/10dKr_yb7eAOmz67RdNPHFUWzo_uVyIyQ/view?usp=drivesdk
(Please scan the file for virus before opening.)
Please let me know after you’ve downloaded it.
Besides, I downloaded and used Typograf, AMP Font Viewer, FontBase and Advanced Font Viewer in Windows 11. All four programs failed to load the 5 invalid font files.
Then, I tried to open the 5 invalid font files in Windows 7 by double-clicking the files in Windows Explorer (not using the four programs abovementioned), all 5 font files couldn’t be opened.
But I saw on the internet that:
1.) some people said that some font files are valid in certain versions of Windows but are invalid in certain versions of Windows, and
2.) some people said that they used online font converter to convert their invalid font files, and then some of the converted font files become valid.
Just that I don’t know when the invalid font files become valid, does the copyright notice, license information, and other information appear back in the properties of the font files or not. If the information is not there when the invalid font files become valid, does this mean that I could be in trouble?
I didn’t try to convert the 5 invalid font files because I don’t know if uploading to the online font converter is considered distribution or not, and I can’t provide any standalone copyright notice and license information.
I got the Source Han Sans and Source Han Serif fonts files that have been converted from OTF into TTF.
I couldn’t remember how I got them but I found a site that seems to have the same files.
- the number of files is the same as those I have
- the filename of the files are the same as those I have, and
- the content in the README.txt file is the same as the one I have
Here’s the link: https://gitee.com/kero990/Source-Han-TrueType
In the properties of the TTF and TTC files, they seem to retain all the information in the original files.
(I don’t have the original OTF/OTC files that are same version as these TTF/TTC files, but I have some of the original OTF/OTC files that are lower and higher version than some of these TTF/TTC files.)
The words “Reserved Font Name ‘Source’” is still in the Copyright statement in the properties of the TTF/TTC files and ‘Source’ is still in the name of the TTF/TTC fonts.
According to the readme file of the TTF/TTC version of Source Han Sans and Source Han Serif fonts:
- Language-specific version: TrueType collection (TTC)
- Region-specific subset version: TrueType (TTF)
- Units-per-em (UPM): 2048, i.e. lossless conversion from the OpenType/CFF source
- Rendering strategy: full-range subpixel anti-aliasing (on Windows 10)
- OpenType features: All included
I have given other people some or all of TTF/TTC version of Source Han Sans and/or Source Han Serif fonts or installed some or all of the TTF/TTC fonts in other people’s devices that I have permission to use, without any standalone file containing the text of the copyright notice and the full text of the license along with the font software. However, the copyright notice and a link to the SIL OFL 1.1 are in the font properties (when I checked with Typograf).
My concern is actually about the Reserved Font Name (RFN).
I don’t know if I have violated the term about the RFN in OFL because RFN of the original font software seems to be used in the TTF/TTC files but I didn’t get permission from the original copyright holder (Adobe) before sharing the files with other people.
Could you please help to check for me?
Thanks, and may you be well and happy!
