The error is below. It looks like GetAttributes is throwing an exception which we are not handling. However the file does exists.... so it should work.

Another question/concern which comes to mind is around NormalizationForm; see also (?):

• https://github.com/xamarin/xamarin-android/commit/578e781ba15326f3141e475977e7d1dc75057a42
• https://unicode.org/reports/tr15/

What gives me pause about this question is that afaik Unicode Normalization only comes in when there is more than one way to represent a given character, e.g. \u202b Å is \u0041\u030a Å in NFD and \u00c5 Å in NFC.

For Chinese characters, there doesn't appear to be a difference in normalization forms, i.e. this is likely not relevant:

var s = "随机生成器";
string.Equals(s, s.Normalize(NormalizationForm.FormC),  StringComparison.Ordinal); // true
string.Equals(s, s.Normalize(NormalizationForm.FormD),  StringComparison.Ordinal); // true
string.Equals(s, s.Normalize(NormalizationForm.FormKC), StringComparison.Ordinal); // true
string.Equals(s, s.Normalize(NormalizationForm.FormKD), StringComparison.Ordinal); // true
