I have looked for this fo java code using ASCII table.
\u001B[1m <- Bold on
\u001B[0m <- Text Stuffs off
drawLoadingText(percentage, (new StringBuilder()).append("\u001B[1mDownloading\u001B[0m "+downloadingText+""+s+": "+percentage+"% ").append("@ "+downloadSpeed+"Kb/s").toString());
this above its find here
In order to apply a style on your string, you can use a command like:
echo -e '\033[1mYOUR_STRING\033[0m'
Explanation:
echo -e - The -e option means that escaped (backslashed) strings will be interpreted
\033 - escaped sequence represents beginning/ending of the style
lowercase m - indicates the end of the sequence
1 - Bold attribute (see below for more)
[0m - resets all attributes, colors, formatting, etc.
The possible integers are:
0 - Normal Style
1 - Bold
2 - Dim
3 - Italic
4 - Underlined
5 - Blinking
7 - Reverse
8 - Invisible
