Yii2: StringHelper::truncate returns a string with more space

[kk8686]

echo \yii\helpers\StringHelper::truncate('我<span>是a中</span>国人', 4, '...', 'UTF-8', true);

When I set param of $asHtml are true, the result is: "我 <span>是a </span>..."

But I'm expect is: "我<span>是a中</span>..."

Seems like unicode issues to me.

1. Have you tried code from master?
2. Any ideas on fixing it?

[kk8686]

I'm sorry I don't have try to code from master, bacause I no any ideas

[samdark]

OK, I'll handle it.

That's not because of UTF-8 but because of adding extra spaces (why?) after tokens here

@samdark Thanks

Isnt this the cause of half widht characters? In the pull ruest for console::table the widh was also off.

Tests has extra spaces too https://github.com/yiisoft/yii2/blob/master/tests/framework/helpers/StringHelperTest.php#L110 that's funny.

I can't remember why I added the extra space there, not sure if it was more for truncating words within HTML that spaces would get lost.
I'll do some more tests to see if that space can be removed.

[alex-code]

The main issue is with spaces getting removed by the truncate and truncateWords methods.
I've updated the truncateHtml method and added new tests which all pass.
