Isn't that just a little ironic that the Unicode bullets have been converted to the prescription symbol?

gregheo2• 14 years ago

I'm pretty sure that's on purpose (Unicode prescription 1, prescription 2, etc.). Or did my <sarcasm> tag detector mess up again?

I love to develop with perl, but unicode-related stuff was always frustrating for me. Probably because I deal with it so rarely and everytime I have to look documentation to find out how to read unicode file, run regexps on unicode strings, etc.

I am wondering, how other major languages deal with unicode? Is there language which work with unicode files/text transparently without /me involving into setting something differently from defaults?

Perl comes out best according to Tom Christiansen (author of this Perl Unicode Cookook post).

See his Unicode Support Shootout - The Good, the Bad, & the (mostly) Ugly presentation at OSCON 2011 where he gave a comparison of Unicode handling in Javascript, PHP, Go, Python, Ruby, Java, and Perl.

Perl is in the lower tier IMHO. Below Python and Haskell. Because while it has a good core unicode support, every single library makes different choices, so your code constantly needs to encode/decode. Javascript seems to avoid encoding issues entirely, at least in the browser, though Tom has some nice points about it not full supporting unicode. <http://kitenet.net/~joey/blog/entry/unicode_ate_my_homework/...;

>Perl comes out best according to Tom Christiansen

It would be hard to find a more bias source.

gregheo2• 14 years ago

Perl is definitely bipolar in this respect -- I've never had an easier time of dealing with Unicode issues than in Perl, but I've also never cursed Unicode so much while dealing with it in Perl.

Could you say in what other languages you dealt with Unicode?

gauravk92• 14 years ago

Python has native support for unicode strings, not Unicode support in native string types. Sigh, this is where it gets into bs world, because you have to figure out how to convert back and forth appropriately. Just thought I'd share my recent frustration.

There's something wrong with the font size of code samples.

pavelkaroukin3• 14 years ago

code snippets tends to be long. so they have font-size: 65% for <code>

I've found increasing font is required anyway, since my browser default font size a bit small for my screen resolution.

Increasing font size is quite easy in most browsers. Hold Ctrl key and use mouse wheel to adjust size. This is per-site setting in most browsers I believe.

obtu2• 14 years ago

I've reenabled Firefox's minimum font size; it's a bit buried in the preferences (fonts->advanced) but it's more effective to fix sites where the sizes lack consistency. For most sites NoSquint works well.

I'd love to have the POD of this locally, but can't seem to find it anywhere. Anyone know where it lives?
