#445 Issues with non-English letters and words

[Altaveron]

ISSUE:

Steps to reproduce issue:

1. Add any English and Russian words on the editor with highlighter.
2. Double-click on the first word and on the second word.

Russian word won't be selected. (There are more issues with non-English words also.)

Russian word should be seleced as English word.

FIX:

The following code works incorrect with non-English letters (for example, Russian):

function TSynCustomHighlighter.IsIdentChar(AChar: WideChar): Boolean;
begin
case AChar of
'_', '0'..'9', 'A'..'Z', 'a'..'z':
Result := True;
else
Result := False;
end;
end;

The correct code is the following (as on TCustomSynEdit.IsIdentChar method):

function TSynCustomHighlighter.IsIdentChar(AChar: WideChar): Boolean;
begin
Result := AChar >= #33;
end;

TODO:

The issue should be fixed on all other modules too. Find all incorrect places by search string "'a'..'z'".
