Titles starting with hyphens do not work

[forthrin]

• [X] I looked in closed issues and it has not already been answered

• [X] My issue appeared with a terminal-notifier update

• [X] I'm using a tool that uses terminal-notifier (guard-notifier, node-notifier...)

• macOS 10.13

• terminal-notifier 2.0.0

• Homebrew

Example:

$ terminal-notifier -title -123 -message 456

[WidgetsBurritos]

This seems to work: terminal-notifier -title "\-123" -message 456

This escapes the hyphen so it's treated as part of the string

[forthrin]

Several other ASCII characters must also be escaped. (Remove four or the backslahes for comparison.)

$ for f in 34 40 42 45 60 91 92 123; do terminal-notifier -title $(printf "\\\\\x$(printf %x $f)") -message $f; done

@julienXX: Shouldn't the application escape these automatically? It's not the shell's responsibility, really.

Other observations regarding string arguments:

1. Spaces and Tabs are left-trimmed, and displayed like expected when inside the string.
2. Everything following a Tab is not displayed
3. Everything following CR or LF only displays "..."
4. Other Control Characters than the above, plus DEL, are ignored anywhere.
5. Unicode characters seem to be working out of the box.
