What could be reasons for this android EditText control to convert the input to the ascii sequence - xamarin.forms

Question

So for some project i'm working with Xamarin.Forms.
Since one area is just unbearably slow with Xamarin.Forms i've used a CustomRenderer to solve one particular area where a list is involved.
After getting back to the project and upgrading packages, i've suddenly got the weirdest bug.
I am setting "1234" to an EditText, and the EditText.Text Property is suddenly "49505152" - the string is converted to its ascii equivalent.
Is this a known issue? Does anyone know how to fix it?

Answer 1

The cause of the issue was that my EditText had an InputFilter applied and that after updating a package suddenly another code path of FilterFormatted was executed.
public ICharSequence FilterFormatted(ICharSequence source, int start, int end, ISpanned dest, int dstart, int dend)
{
var startSection = dest.SubSequenceFormatted(0, dstart);
var insert = source.SubSequenceFormatted(start, end);
var endSection = dest.SubSequenceFormatted(dstart, dest.Length());
var merged = $"{startSection}{insert}{endSection}";
if (ValidationRegex.IsMatch(merged) && InputRangeCheck(merged, CultureInfo.InvariantCulture))
{
StringBuilder sb = new StringBuilder(end - start);
for (int i = start; i < end; i++)
{
char c = source.CharAt(i);
sb.Append(c);
}
if (source is ISpanned) {
SpannableString sp = new SpannableString(sb);
TextUtils.CopySpansFrom((ISpanned)source, start, sb.Length(), null, sp, 0);
return sp;
} else {
// AFTER UPDATE THIS PATH WAS ENTERED UNLIKE BEFORE
return sb;
}
}
else
{
return new SpannableString(string.Empty);
}
}
