* [R-package] [docs] Simplified examles to cut example run time (fixes #2988)

* updated learning rates

* Support UTF-8 characters in feature name again

This commit reverts 0d59859c.
Also see:
- https://github.com/microsoft/LightGBM/issues/2226
- https://github.com/microsoft/LightGBM/issues/2478
- https://github.com/microsoft/LightGBM/pull/2229

I reproduced the issue and as @kidotaka gave us a great survey in #2226,
I don't conclude that the cause is UTF-8, but "an empty string (character)".
Therefore, I revert "throw error when meet non ascii (#2229)" whose commit hash
is 0d59859c, and add support feture names as UTF-8 again.
