Fix trim throwing regex error

[apstanisic]

Description

JS is throwing error if charsToTrim has some special value.
In this example, trim(" __-_ hello", "_- "), _- is treated as a range, but that range is invalid.
In this PR, every value that is not ascii char, number, or underscore (\W) is escaped.
There is maybe better way to do this, I'm not sure.
I'm not sure if this fixes all posibilities, especially with emojis and unicode, I'm not familiar enough.
