unicode - (grep) Regex to match non-ASCII characters? -

-

On Linux, I have a lot of files, some of them have non-ASCII characters, but they all are valid. There is a bug in a program that prevents it from working with non-ASCII filenames, and I have to find out how many impressions I was going to do with this search and then the non- ASCII used to print the characters, and then do a wc -l to find the number. It does not have to be grep; I can use any standard UNIX, such as ,,, etc.

However, is there a regular expression for 'any letter that is not ASCII character'?

This will match a non-ASCII character: 

  [ ^ \ X00- \ x7F]

This is a valid ( Perl-compatible regular expression ).

You can also use the shorthound:

  • [[ascii:]] - matches a single ASCII character
  • [^ [: ascii:]] - matches a single non-ASCII letter

[^ [: Print:]] Maybe it will be enough for you. **

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
