<p>I copied and pasted the following code from <a href="https://github.com/nickboucher/trojan-source/blob/main/C/commenting-out.c">trojan-source</a><br>
<a target="_blank" rel="noopener noreferrer" href="https://user-images.githubusercontent.com/1738012/140482937-700db336-355f-4df8-9c19-08b50d0e265a.png"><img src="https://user-images.githubusercontent.com/1738012/140482937-700db336-355f-4df8-9c19-08b50d0e265a.png" alt="geany-right-to-left" style="max-width: 100%;"></a><br>
As you see, line 6 is not rendered properly.<br>
The curly braces inside RLI are unreachable by mouse or arrow keys movements.<br>
When the same code is saved as text, the curly brace on line 8 changes from close to open as the cursor moves to the curly brace on line 9.</p>
<p>And, yes, there are <a href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-42574" rel="nofollow">security concerns</a> involved.  <a href="https://www.trojansource.codes/" rel="nofollow">Read more</a></p>
