/**

* @ Desc get the first letter of the string

* @ Param $ string the string to be converted

* @ Param $ whether isOne is the first letter

* @ Param $ whether the upper is converted to uppercase

* @ Return string

*

* For example, getChineseFirstChar ('I am the author') must start with all letters and lowercase letters.

* Return "wo"

*

* For example, getChineseFirstChar ('I am the author', true) first letter + lower case

* Return "w"
