Certain characters prevent later text from rendering about richtextfx

I have reported the bug to Oracle's bug database now. I also discovered "த" + "文".repeat(32_001) + "b" is rendered as தb, unlike "த" + "a".repeat(32_001) + "b", which is rendered த.

This happens with TextArea as well, so I think it's a limitation of Text nodes and probably has something to do with the number of Unicode characters allowed.

I'm guessing that with just plain characters, Text can handle 64K characters but if there's a single Unicode character then it halves to 32K.

Each style is split into its own Text node, so that's why the workaround works when you add a style at 32K.

Ah, I didn't notice it was a bug in TextArea as well. I also tested with a Text node and the behaviour is the same.

I'm not sure what you mean by "Unicode characters", but other characters with higher code points (such as 文) don't trigger the bug. No matter how many characters are in the segment I can't get the bug to occur unless த or one of the other specific characters I know of are used. All of the above is true with Text and TextArea as well.

Great :-)
