Information

• OS: Windows 7
• Version: 0.47.0
• Terminal: Windows Terminal

Describe the bug What I wrote is a console application. It runs without problems on Windows 10, but an ArgumentOutOfRangeException exception is thrown on Windows 7.

Additional context Stack trace:

@lisenz Thanks. Can you show the code so we can reproduce this?

                var oriSubDirs = new string[] {
                    "佛山行政智慧安防",
                    "江门行政智慧安防",
                    "南方基地智慧园区",
                    "汕尾行政智慧安防",
                    "韶关行政智慧安防",
                    "深圳行政智慧安防",
                    "阳江行政智慧安防",
                    "云浮行政智慧安防",
                    "湛江行政智慧安防",
                    "中国移动南方基地6号地"
                };

                AnsiConsole.MarkupLine($"1.[yellow]共{oriSubDirs.Count()}个巡检项目：[/]{Environment.NewLine}");
                var itemsPerLine = 5;

                var table = new Table();
                for (int i = 0, len = oriSubDirs.Count(); i < len; i++)
                {
                    var oriPro = oriSubDirs[i];
                    table.AddColumn($"[yellow]{oriPro}[/]");
                    if ((i + 1) % itemsPerLine == 0)
                    {
                        AnsiConsole.Write(table);
                        table = new Table();
                    }
                    if (len < itemsPerLine && i == len - 1)
                    {
                        AnsiConsole.Write(table);
                    }
                }

@patriksvensson Hi，I Copied from my own project and add some test data.

I've managed to reproduce on my machine with 100x32 console window size, but I think OS doesn't matter here. The exception occurs when the row text is too long and SplitOverflow method is called. I guess Windows 10 sets larger console size by default.

The root cause is that some symbols have different length in console and as a member of string in .NET. E.g.

"𧼢".Length // 2
Cell.GetCellLength("𧼢") // 2

"中".Length // 1
Cell.GetCellLength("中") // 2

"A".Length // 1
Cell.GetCellLength("A") // 1

I can fix it by truncating a string with regard to space it takes up in console. @patriksvensson what do you think?

@etherfield Hi, Is it because the table.AddColumn() method has a length limit on the text content passed in? Once the text length is too long, will it be automatically intercepted and cause an exception?

[etherfield]

If a text is too long is should be truncated, but it causes an exception instead. This is Windows 8.1. I don't have all the characters (hence '?' marks), but nevertheless the screenshot below is to illustrate what I'm talking about.

In fact, this is how the fix may look like: 1342-argument-out-of-range
