Issue with Unicode input on `GuiTextBox()` #399

Open electrolys opened 3 months ago

electrolys commented 3 months ago

gui textbox doesn't handle adding and removing characters properly and causes an underflow (at adding) and overflow (at removal)

you are just comparing the variable i with the text length or cursor when you really need to >= cursor+codepointsize and <= length-codepointsize
