Would be nice if the editor could save new files with a predefined charset.

My employer use ISO-8859-1 as default charset and I have to change this everytime I save a new file.

In Vim 7.3 they added a really nice feature allowing to display some syntax regions (selectors) as configurable unicode characters. It makes much easier to read some languages, like the following example for Javascript where "function" has been replaced by "𝑓", "this." by "@" and "return" by "↩" .

With the recent inclusion of code folding, which allows for "inline" folds, I think the editor is ready to implement this feature without much effort. 

I've tried to implement a plugin for this but I'm lacking one API function, which could work just like View.fold but allowing to set a custom character and syntax selector for its display, instead of the currently hardcoded fold icon.

class LineZero(object):
    first_line = "bar"
    def second_line(self):
        third_line = "baz"
        fourth_line = 42

    first_line = "bar"
    def second_line(self):
        third_line = "baz"
        fourth_line = 42
        fifth_line = 5

class LineZero(object):
    def second_line(self):
        third_line = "baz"
        fourth_line = 42
        fifth_line = 5

class LineZero(object):
    def second_line(self):
        fourth_line = 42
        fifth_line = 5
        sixth_line = None

If indentation settings are "indent using spaces", then auto-indentation and the TAB key should insert spaces.

When a TAB character ("\t") is pasted from the clipboard, it should remain a tab character. 

This post explains the problem well. Hash tags like "end" and "class" in the new 1.9 Hash literal format are hightlighted incorrectly. The post contains a fix that works perfectly, namely to edits the Ruby language file by moving the block of code at lines 201-208 to line 1570.
