ruby - Isn't user data that comes in from a form in Rails going to be UTF-8 encoded? -

a rails 3.2 app i'm contributing has method coerces user input utf-8.

require "iconv" def normalize(user_input_text) iconv.new('utf-8//ignore', 'utf-8').iconv(user_input_text.dup) end

it encodes string in utf-8 , ignores characters can't transcoded.

but isn't user info that's entering rails through form going utf-8 encoded?

in other words, isn't code specious , unnecessary?

these resources suggest indeed right.

now vast bulk of web input utf-8, set inbound parameters utf-8. eliminate many cases of incompatible encodings between ascii-8bit , utf-8.

https://github.com/rails/rails/commit/25215d7285db10e2c04d903f251b791342e4dd6a

rails 3 solves nicely doing number of things including interpreting params utf-8 , adding workarounds net explorer

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
