We previously used a text that appears to be an excerpt of
https://zh.wikipedia.org/wiki/%E5%8D%97%E8%B6%8A%E5%9B%BD
and can have copyright/license complications. It may
also include some geopolitical nuances. The text has been
repeated through out the code base without much reuse.
This patch consolidates the fixtures by adding a common helper
string as `fixtures.utf8TestText` which is identical to a copy
in test/fixtures/utf8_test_text.txt. It also updates the text
to a copy of 蘭亭集序, It was chosen because:
1. It's a well-known Chinese classical piece written in 353 CE
and therefore in public domain. The string is copied from
https://zh.wikisource.org/zh-hant/%E8%98%AD%E4%BA%AD%E9%9B%86%E5%BA%8F
which contains a disclaimer of copyright for this reason.
2. The text is in suitable length for general UTF8 string
read/write tests (including punctuations, 389 code points and
1167 bytes).
3. This is also commonly used as reference text for Chinese text
layout tests.
4. It's a timeless and harmless preface for a collection of poems,
written by a uncontroversial figure who passed away >1600 years
ago and contains no geopolitical nuances. Background and an
English translation of this text can be found at
