With regard to recent Normalization changes I have just run our test
suite with recent mono r136422 - and are getting a number of
string styleName = "\u00e1bc";
StStyle style = new StStyle();
style.Name = styleName;
FwStyleSheet.StyleInfoCollection styleCollection = new
Assert.IsTrue(styleCollection.Contains(styleName.Normalize(NormalizationForm.FormC))); Assert.IsTrue(styleCollection.Contains(styleName.Normalize(NormalizationForm.FormD))); Assert.IsTrue(styleCollection.Contains(styleName.Normalize(NormalizationForm.FormKC))); Assert.IsTrue(styleCollection.Contains(styleName.Normalize(NormalizationForm.FormKD)));
is now failing, as well as other larger unit tests.
I will look info this further to try and produce an example test program
that doesn't contain references to our code base.
