+# UnicodeCharsGenerator
+## Ever seen some of these weird looking Unicode characters on the Internet ? Time to find more )
+
+# Usage
+## There are 2 flags to specify - `-inline` and `-limit`
+`-inline` flag takes an integer. If not negative - each line in the output file will contain specified number of characters
+`-limit` flag takes an integer. If not negative - the output file will contain all Unicode characters up to specified one   
+
+## Examples
+
+### `-inline`
+1. `./UnicodeCharsGenerator -inline=20` - the generated output file will **try** to contain 20 characters in one line
+2. `./UnicodeCharsGenerator -inline=-1` - all characters will be put in one line
+3. `./UnicodeCharsGenerator` - as in 2., all characters will be put in one line  
+
+### `-limit`
+1. `./UnicodeCharsGenerator -limit=20000` - the generated output file will contain all Unicode characters up to 20000 one
+2. `./UnicodeCharsGenerator -limit=-727` - the limit is ignored and you will get **all 10FFFF** Unicode characters
+
+### general
+1. `./UnicodeCharsGenerator` - all Unicode characters, all in one line
+2. `./UnicodeCharsGenerator -limit=900 -inline=5` - 900 first characters, only 5 characters on one line
\ No newline at end of file
