Profiles: Cyrillic entries from local support forums are limited to just a few words

[SergeyBiryukov]

Since #129, profiles include activity from local forums as well.

We've found two issues with the implementation, see an example on ​https://profiles.wordpress.org/sevlad:

• Cyrillic entries are cut off to just a few words instead of a meaningful sentence.
• If the reply starts with someone else's quote, the activity entry displays that quote instead of the actual reply. If the quote is short enough, it's a mix of both, but without any markup to separate them.

For a language where most words are longer than in English, this doesn't make much sense:

Дайте наводку… Выкинуть все…
Не все же на сайте для посетит…
Обьем рубрики должен выйти на…

To get a feeling of what it looks like to a Russian user, here's a translation :)

Give me a hint… Throw away…
Not everything on the site is for visit…
Category size should be…

English entries, on the other hand, are noticeably longer, see the screenshot.

Looking at [3920], reply excerpt should have 55 characters per bbp_get_reply_excerpt( $reply_id, 55 ), but it only has ~27 or so.

• Perhaps mbstring is not enabled?
• Any chance to use wp_trim_words() to cut by words instead of characters?
• If wp_trim_words() cannot be used, any chance to increase the length to at least 80 characters?

In 3931:

Profiles Activity Notifier: Improve reply excerpt generation.

• Use newly introduced get_reply_excerpt() instead of bbp_get_reply_excerpt().
• Strip all blockquoted text from excerpts since that text is not original to the reply.
• Trim reply excerpts by words (15) instead of by characters.
• Add trim_text() to handle trimming text by words or by characters.
• If trimming by characters, honor requested excerpt length for multibyte strings.

Fixes #1953.
