Problems with character sets

•  Extra metadata •  Potential for misdisplay •  Mutually exclusive •  Little space to grow - e.g. € •  Ideographic languages – 70,000+ Chinese characters – Multibyte encoding


Lecture 11



The Unicode solution

•  One global character set – Over 110,000 characters – Over 100 alphabets

•  1,114,112 code points – 0…255 compatible with ISO-8859-1 – U+0041 = A

•  Multiple encodings


U+0000 … U+007F


U+0080 … U+00FF


U+0400 … U+047F


U+0590 … U+060F


U+4E00 … U+4E7F


U+2190 … U+220F


U+2800 … U+267F


UTF-16 encoding

•  2 or 4 bytes per code point •  Simple for U+0000…D7FF and E000…FFFF – “Basic Multilingual Pane”

•  Higher code points use 4 bytes •  U+FEFF = byte-order mark – No well-followed default

•  Windows APIs since Windows 2000 – Also .NET, Android, iOS, Mac OS X


UTF-8 encoding

•  1 to 6 bytes per code point •  1 byte for U+0000…007F – Perfect compatibility with ASCII

•  2 bytes for U+0080…07FF – etc…

•  Byte order mark allowed – But unnecessary, causes problems

•  Dominant on web, email


UTF-8 encoding


UTF-8 advantages

•  Natural compression for English •  English works in old tools/APIs – HTML tags unaffected

•  No shared values between byte types – Easy to synchronize mid-stream – Easy to search by byte value

•  No zero bytes (good for C) •  Byte-sorting = codepoint-sorting

The original source code


function Check_Username(username) … if Username_Taken(username)… error="username is taken." … return error end function

And now in Spanish…

function Check_Username(username) … if Username_Taken(username)… error="username se toma." … return error end function


Internationalized

function Check_Username(username) … if Username_Taken(username)… error=Get_String("un-taken") … return error end function


Internationalized

function Check_Username(username) … if Username_Taken(username)… error=Translate("username is taken") … return error end function From Code to Product Lecture 11 — Localization— Slide 39 gidgreen.com/course

IDs vs English strings


IDs English strings

More compact code More explicit code

English can be changed Enforces sync between languages

Less error-prone Easier for third parties

Concatenation is evil

print Translate("You will travel from ") + from_city + Translate(" to ") + to_city


You will travel from London to Paris

Usted viajará de London a Paris

Sie wird von London nach Paris reisen

Substitutions


raw=Translate("You will travel from %from% to %to%") raw=replace(raw, "%from%", from_city) print replace(raw, "%to%", to_city)

You will travel from %from% to %to% Usted viajará de %from% a %to% Sie wird von %from% nach %to% reisen

Singular/plural

if (credits is 1) c_string=translate("1 credit")

else c_string=replace(translate("%#% credits",

"%#%", credits) raw=translate("You have %credits% left”) print replace(raw, "%credits%", c_string)


You have 3 credits left You have 1 credit left

Time zones


Map from wikipedia.org

Displaying times online

•  Store times independent of zone •  Options for display – Ask the user for their time zone – Show an explicit time zone – Use “ago” notation

•  Javascript to get from browser


Currencies

•  Biggest traded currencies: $ € ¥ £ – But there are almost 200

•  How to display – Number formatting – Symbols: ₪ ₩ ฿ $ – Currency codes: USD EUR JPY GBP CAD AUD

•  Also: currency conversion – Live feed, e.g. from ECB


Names

•  Surname can come first – China, Japan, Korea, Hungary

•  Multiple surnames – José Santos Tavares Melo Silva

•  Middle names/initials •  Double-barrelled names – Sarah-Jane Darlington-Whit

•  No spaces in CJK


Names


Full Name:

What should we call you?

Family name:

Other/given names:

•  Or localize based on language •  Do you need names at all? – Username or email can be enough

Addresses


John Doe Acme, Inc Suite 3B-3824 294 W Ronson Dallas TX 75211 USA

John Smith Acme, Ltd Flat 384 33 Walton Road Birmingham B26 3QJ UK

〒100-8994 東京都中央区八重洲一丁目5番3号東京中央郵便局 Tokyo Central Post Office 1-5-3 Yaesu, Chuo-ku Tokyo 100-8994 Japan

C/Pescadoro, 13, 2°, 3ª 28331 – Madrid Spain

Addresses

•  Single multi-line field •  Change in response to country •  Generic format


Indexing, sorting, searching

•  Capitalization and accents – Øyvind matches oyvind?

•  Collation (sort order) – Swedish: a b c … x y z å ä ö – French: cote côte coté côté

•  CJK (ideographic languages) – No spaces between words – Sort based on stroke count


Domain names

•  Country-code top-level domains – .fr .de .uk .in .br .jp .cn

•  Need separate registrar for many •  Some countries have restrictions – .com.au requires registered company – .ca requires nationality/residence – Also restricted: .fr .br .cn .ie .jp …

•  Internationalized domain names


And there’s more…

•  Phone numbers •  Units of measurement •  Colors •  Images of people •  Calendars •  Border disputes •  Culture •  Law From Code to Product Lecture 11 — Localization— Slide 60 gidgreen.com/course

Google in China

•  2005: Chinese language google.com •  2006: google.cn under censorship •  2009: China blocks YouTube •  2010: Google claims hacking attack – Redirects google.cn to google.com.hk – China blocks it for a day

•  Today: Baidu 79%, Google 17% – Baidu links to MP3/movie downloads


Getting real

•  It’s time consuming and costly •  Cheap wins in version 1.0 – Parameterize + functionize – Use Unicode throughout – Flexible layouts

•  See where there is demand –  Identify most important locales


Getting real

•  Don’t skimp the details – Needs to look native

•  Use serious service providers •  Prepare for tech support – Machine translation an option?

•  It will slow development – So wait for product maturity
