utf 8 - Character encoding - copy/paste from web -


this more educational question character encoding (hobbyist coder here) - have encountered specific problem:

1) wrote silly program in python 3, in editor using utf-8 (german keyboard here).

2) share "creation" interested family-members... pasted code private pastebin.com (with instructions: copy/paste (raw) file text-file , change file extension .py)

here trouble starts:

3) following these instructions not allow run program.

4) not sure why doesn't work, since character-encoding ansi know problem. changing encoding utf-8 in code-editor solves problem.

the questions are:

a) why change ansi?

b) why doesn't work anyway in ansi (since eye whole code looks same)

c) how conserve utf-8 encoding? mean: family doesn't know how change encoding... (i know... send them executable file. said... educational)

edit: clarified python-3.x version

when copy paste text editor , press save, that's trouble starts. when saving, must specify encoding, or @ mercy of default "ansi". text file cannot saved without using kind of encoding.

it might not work because have declared # -*- coding: utf-8 -*- in file, text editor saving file in "ansi" has no knowledge of , leave of course. parser try read file utf-8 , fail because it's not utf-8.

you use \uxxxx escapes non-ascii characters in source.

so instead of:

str = u"€"

do 

str = u"\u20ac"

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
