Parser fails on } { sequence

[tomaszkruzel]

After trying to call IconTextView.setText with text that contains { } in reversed order,i.e.:
text}{
text}text{text

ParsingUtil fails with error:

java.lang.StringIndexOutOfBoundsException: length=37; regionStart=36; regionLength=-37
at java.lang.String.startEndAndLength(String.java:504)
at java.lang.String.substring(String.java:1333)

at com.joanzapata.iconify.widget.IconTextView.setText(IconTextView.java:34)

I am aware that { } is a pattern. But I believe reversed order of } { could be detected by the parser to avoid the crash.

In my case this part of iconified text comes from user input, so I am forced to sanitize the text.
