Package Exports

cleanstr

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cleanstr) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cleanstr

Some characters we can't see them on the text editor, but they really exist. They may be indifferent for your programs, but sometimes not. For example, you try to set default values for the talbe fields on database, but the default values are read from some files that may contain special chracters or zero-width chracters. And then you may get the error: invalid character for default value!. So let's remove these unwanted charaters.

Special characters

Unicode character value	Escape sequence	Meaning	Category
\u0008	\b	Backspace
\u0009	\t	Tab	White space

\u000B	\v	Vertical tab	White space
\u000C	\f	Form feed	White space
\u000D	\r	Carriage return	Line terminator
\u0020		Space	White space
