Line break with Russian Language

[Aqoolare]

Describe the bug

Line break does not work when using the Russian language.

To Reproduce

Steps to reproduce the behavior:

1. Add a string "Число d > 0 называется наибольшим общим делителем (НОД) двух целых чисел a и b, если оно удовлетворяет следующим условиям: 1) d | a и d | b; 2) если c | a и c | b, то c | d." to the LaTeX field of the TextView.

Expected behavior

Words are wrapped to a new line at the end of a word

Environment (please complete the following information):

• Platform: [CSharpMath.Forms]
• Package Version or Commit: [0.5.0]
• Device: [Pixel 2 Q 10.0]

Additional context

I really need to solve this problem :(

Thank you very much for your prompt answer, but I am having problems using the given solution.
But I have some problems with its application, I attach screenshots with errors. And also I have a question, where should this code be placed in the project?

@Aqoolare The change is not published yet, I'll publish a 0.5.1 and you can use that code.

Also to use C# 9 which I've used, you must add <LangVersion>latest</LangVersion> to the <PropertyGroup> inside your .csproj.

You can also add your own line breaks with \\ or reduce the font size.

Ok, thank you very much for such prompt support.

Guys, I found how to solve the display problem! I used the wrapper this way public class MyTextView : TextView { public MyTextView() { InvalidateSurface(); } }
And used it on xaml this way <views:MyTextView x:Name="textView" LaTeX="{Binding Formula}" Margin="15, 5" FontSize="43"/>
But issue with the words wrapping remains

Maybe I don't understand where to put this code CSharpMath.Rendering.Text.TextLaTeXParser.AdditionalBreakingEngines.Add(new RussianBreakingEngine());

This thread is getting overloaded with different issues so I've hidden everything not related to line breaks. Please post other issues if you have unresolved questions not relating to line breaks @Aqoolare . Thanks.

Currently CSharpMath uses Typography.TextBreak, so one option is to wait for Typography.TextBreak to resolve the issue that @Happypig375 posted.

I'm not convinced that text breaking is difficult enough to require a separate engine. Can't we break on spaces and hyphens only? LaTeX doesn't usually support automatic hyphenation and I assume we have no plan to support that, so breaking should be easy shouldn't it?

Overleaf breaks on spaces and commas but not punctuation:

My other problems have been resolved, thanks, the only thing I would like to clarify, that is, at the moment the transfer by Russian words does not work?

Even with this code 'CSharpMath.Rendering.Text.TextLaTeXParser.AdditionalBreakingEngines.Add(new RussianBreakingEngine());'?
