There are a lot of examples of Japanese text in which Western and/or Greek letters are mixed among Japanese letters.

"Western and/or Greek letters" should probably be "Latin and/or Greek letters". We found this during a CLReq meeting.

[himorin / Atsushi Shimono]

Looking around text with "Western" within whole text, and considering founding like:

• Japanese and Western mixed text composition is described as To mix Japanese text and Western text in the same composition.
• character class cl-27 is named as Western characters, which includes several others than Latin and Greek characters
• Words Letter and Character are often in mixed use, like Jizura is written as Letter face as terminology.

it is not fixed easily just by replacing Western with Latin, which is also not correct per traditional(?) Japanese writings.

So, how about as PR #366 ?
