Martian language

Martian language (: 吙☆魰) is the nickname of unconventional representation of Chinese characters online. "Martian" describes that which seems strange to local culture. The term was popularised by a line from the 2001 Hong Kong comedy "Shaolin Soccer", in which Sing (Stephen Chow) tells Mui (Zhao Wei): "Go back to Mars. The Earth is so dangerous."
In the 2006 General Scholastic Ability Test of Taiwan, students were asked to interpret symbols and phrases written in "Martian language", and the controversies which followed forced the testing center to abandon the practice in future exams.
In 2007, Martian language began to catch on in mainland China. The first adopters of Martian language mainly consisted of Post-90s netizens. They use it in their nicknames, short messages, and chat rooms in order to demonstrate personality differences. Later, they found that their teachers and parents could hardly figure out their new language, which quickly became their secret code to communicate with each other.
The Martian language became so popular in cyberspace that even some pieces of software were created to translate between Chinese and Martian language.
Chinese online bloggers followed up the trend to use Martian language, because they found that their blog posts written in the new language can easily pass Internet censorship engines, which are currently based on text-matching techniques.
General aspects.
The Martian language is written from Chinese by means of various substitution methods. Just like in l33t, where the letter "e" is replaced by the number "3", in Martian, standard Chinese characters are replaced with nonstandard ones, or foreign scripts. Each Chinese character may be replaced with:
For example, the 星 in 火星文 "huoxingwen" (星 is literally "star"; 火星 is "Planet Mars") can be replaced by "☆", a Unicode symbol that visually represents an actual star. 的 is commonly replaced with の, as it has the same intended meaning in Japanese. 火 can become 吙 just by adding a 口 radical, which alters very little in terms of sound (but changes the meaning), and visually maintains the 火 image. In the same principle, 文 "wen" ("language") can be replaced with 魰 by adding a 鱼 "fish" radical, which makes the character still look similar. Also, 的 is sometimes replaced with "d" due to its sound, as with 比 being replaced with "b"; Cyrillic can be used in a similar manner. 
Brain-disabled characters () are a subtype of Martian: BDC only includes Chinese characters and nothing else, while Martian language incorporates BDC, as well as scripts such as Cyrillic, Hiragana, Bopomofo, SMS, and others.

English translation.
Whereas recognition of the inherent dignity and of the equal and inalienable rights of all members of the human family is the foundation of freedom, justice and peace in the world,
Whereas disregard and contempt for human rights have resulted in barbarous acts which have outraged the conscience of mankind, and the advent of a world in which human beings shall enjoy freedom of speech and belief and freedom from fear and want has been proclaimed as the highest aspiration of the common people,
Whereas it is essential, if man is not to be compelled to have recourse, as a last resort, to rebellion against tyranny and oppression, that human rights should be protected by the rule of law,
Whereas it is essential to promote the development of friendly relations between nations...
