Saving an UTF-8 file

Miquel Oliete

Hi All

I have a problem (newbie problem).

I don't know how to write a file using utf-8 encoding. Can you help
me.

Thanks in advance

Kind regards

utf-8 is simply 8-bit bytes. Save your data like this:

# "data" contain the text data

File.open(file_path,"w") { |f| f.write data }

utf-8 refers to a convention regarding the content of the bytes and how they
are interpreted when read. It isn't something you can specify in a
plain-text file. It can be inferred from the format of the bytes, but that
is an open interpretation.

Byte order mark?

A specification it is not, but generally a good hint. There are gotchas
though if you process it with software that's not Unicode-unaware.

Not meaningful in UTF-8, since it's all a defined series of bytes
(it's always the same order on all platforms).

Yes, but it can be used as a "this file is UTF-8" marker by convention.
And cause problems in software that doesn't recognize the convention,
for added hilarity.

It's a bad convention, because it adds meaningless bytes to the
beginning of a file. I'm not saying that an unadorned document is
better, but better to do something that has actual meaning than doing
a pointless BOM.

Well, how are you storing the Unicode characters are you using
internally? If your Unicode string within Ruby is stored as an array
of ints, then

File.open("output_file.utf8") do |fp|
fp.puts(data.pack("U*"))
end

should be sufficient. If you have a Ruby string that uses some other
encoding (e.g. ISO-8859-1), then you must use the iconv library to
convert the string to UTF-8:

require 'iconv'

cd = Iconv.new('utf-8', 'iso-8859-1')
File.open("output_file.utf8") do |fp|
fp.puts(cd.iconv(data))
end

When you do i18n, l10n, and m17n, strings become meaningless unless
they have an attached encoding.

Actually I don't mind him as Foreign Minister or as PM - if only he
could control his spending.

I just wish that the ALP would decide who it is who *is* the foreign
minister.

So your philosophy is to vote for people if they are well known. Pretty
shallow really.

If you do a lot of work you run up a lot of costs. The test is whether
the benefits acrued outway the costs incurred. We will have to wait
for history to find out.

That was Bob last time I checked. Bob Carr is the Minister responsible
for foreign affairs. Its his job to manage foreign relations on behalf
of Australians. Mnagement is the process of dealing with or
controlling things or people. A manager adds value to the organisation
through the efforts of others. Rudd, for example.

The current crop of Liberals don't understand management. They are
obsessed with position and think the leader should do everything
personally. That concept doesn't scale past branch level.

Tony is just doing what he has always done. Sometimes it works (as
with Pauline Hanson), sometimes it just makes him look like a goose.

I shudder to think what would happen if he went through this routine
in geopolitics.

I doubt that. But then I know how the Libs fund their campaigns. (How
every Party in government funds its campaigns)

My philisophy is not to vote for people I think are going to harm me,
my family and my country. Once I've eliminated the obvious I consider
who to vote for from those that remain. I'd really love to vote
Liberal again, but I won't while Tony heads the lineup. Even Malcolm
would be better.

Normally financially rational people do a business case first.

A lot of activity also amounts to 'brownian motion' - pressure in all
directions and no forward direction.

Thank you for an excellent metaphor of the Rudd era.

Officially he is but he hasn't achieved anything of significance and he
wasn't elected, so I have serious doubts about him representing us.

Ho-hum. 'Abbott Abbott Abbott'

The investigation into the fraud/incompetence of the PM was not
initiated nor led by Abbott. The fact that you say so illustrates that
you've succumbed to the propaganda and you're a mark.

Why cannot Julia Gillard answer some straightforward questions?

Unionists with a brain would by now be realising that they'd be better
off with a government that doesn't destroy jobs and doesn't ramp up
immigration and makes it easy to do business, which in turn creates jobs.

Female unemployment has risen under Rudd/Gillard's faux feminism and
covert ultra-leftism - as it always does. Women want and need part-time
jobs and flexible jobs & Gillard is instating rigid union rules and
regulations - the result is loss of jobs. Women's unemployment has gone
from 4.4% to 5.2% under Gillard. Real unemployment has double since 2007
from 600,000 to 1.2m and yet the Gillard ALP has ramped up immigration
by 25% *despite* promising a 'population debate' without hurtling toward
a 'big Australia'.

Tony Abbott is honest and his volunteering shows where his heart is.

The campaign by the ALP to demonise him is typical ALP ad-hom politics.

What routine?

A union official starts defrauding the unions and its members and you
get suckered into a belief that it is due to Tony Abbott?
Jeez, you are delusional!

Well mine is similar. I eliminate everyone who lies - which is why I
campaigned against Howard.

And everything you say about Tony Abbott is fed to you by the ALP
propaganda unit.

The outcomes are definitely worth the costs.
Whether we get the outcomes or not we will have to wait for history to
