File cannot be opened when certain Asian characters are added to text layers



I have verified from our issue tracking system and like to share that the issue is tentatively going to get resolved in upcoming Aspose.Imaging for .NET 18.10. We will share the feedback with you as soon as the issue will be fixed.


I tested the issue with 18.11 - thing is that it only solves very small subset of problematic characters, namely Chinese Simplified. Full solution needs to address all Asian characters, please look into these (there could be others as well:

  1. 20941 characters from the CJK Unified Ideographs block.
    Code points U+4E00 to U+9FCC.

U+4E00 - U+62FF
U+6300 - U+77FF
U+7800 - U+8CFF
U+8D00 - U+9FCC
2) 6582 characters from the CJKUI Ext A block.
Code points U+3400 to U+4DB5. Unicode 3.0 (1999).

  1. 42711 characters from the CJKUI Ext B block.
    Code points U+20000 to U+2A6D6. Unicode 3.1 (2001).

U+20000 - U+215FF
U+21600 - U+230FF
U+23100 - U+245FF
U+24600 - U+260FF
U+26100 - U+275FF
U+27600 - U+290FF
U+29100 - U+2A6DF
3) 4149 characters from the CJKUI Ext C block.
Code points U+2A700 to U+2B734. Unicode 5.2 (2009).

  1. 222 characters from the CJKUI Ext D block.
    Code points U+2B740 to U+2B81D. Unicode 6.0 (2010).

  2. CJKUI Ext E block.

It’s still the same file, same code as when I started the thread - not sure what else you need. I specified which characters are causing issues and defined their Unicode ranges.
Note - without this working, the library is quite unusable.
