Question
Why is Label trimming more than 3 consecutive' ' spaces? (godot3.6,4.3)
Why can't see emojies in my UTF8-xplorer'? (godot3.6)
Hello there.
Deving a complex ascii art game and been struggling to put the actual contents of some well crafted text files with ASCII art on Label objects. As you might expect from title, ascii art txt files are getting their lovely white spaces removed, and is hard to input certain characters at center locations. I understand this can be desired behavior for most users, but breaks ascii art. If any experienced dev could point me to the Label trimming white spaces code, or an easy way to bypass this would be great. Using a single Label object with the full string from an ascii art .txt file on resources and you will notice above 3 spaces next characters are shifted and breaks art alignment. even using unicode space with no breaks still gets eaten/trimmed.
Also extending support to emojies, so i devved a nice UTF8-xplorer attached here for you to try it out, having a hard time to find the actual ranges for specific emojies (you can use the slider or the arrow keys, i can see some chars and occasionally some emojies, but never the expected emoji map i need to make to make this game happen). I tried the emoji addon which works, but in need of rawer access to emoji gen. Also you need an emoji font, tried a couple already, still not there yet.
Would be great to hear some input, if you can chyme in please do.
See you around ~
