Rails Excel 2007 export: Add Byte Order Mark to .erb template -


i exporting data excel making erb template xls file. following procedure recommended in railscast 362 making encoded exports.

the output opens fine in excel mac 2011, in excel 2007 characters é appear é because utf-8 encoded file being interpreted excel latin1.

according this answer excel 2007 correctly interpret utf-8 file if starts right byte order mark (bom).

taking @ @ hex version of output seems indeed doesn’t have bom.

there number of sources (like this plataformatec blog post) explain how add bom when rendering data inline in controller:

bom = "\377\376" bom + iconv.conv('utf-16le', 'utf8', data)

my question – there way of getting template correctly interpreted excel 2007? or should go rendering data in controller?

i don't know why excel makes hard, do.

i tried using code myself when ran encoding problem. couldn't figure out how apply working with. did workaround instead.

i downloaded csv file indicated in railscast. opened file textwrangler, encodes properly. then, copied , pasted contents blank excel document (which reads text, , thus, not mess encoding). following that, selected column data fell under, , in menubar selected "data -> text columns". selected delimited list , entered comma delimiter (it defaults tab). finished , voila, there formatted excel doc.

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
