Bug ID: 64244
Summary: [PATCH] Fix exception from using applyFont for unicode
representation _xHHHH_
Product: POI
Version: 4.1.2-FINAL
Hardware: PC
OS: All
Status: NEW
Severity: major
Priority: P2
Component: XSSF

Add testUtfDecode_withApplyFont and patch XSSFRichTextString.getFormatMap
If you use `applyFont()` for `XSSFRichString` having unicode representation
_xHHHH_ format, an IllegalArgumentException is thrown.
`testUtfDecode_withApplyFont` is a new test made by myself, also in the patch.
> Text length was 8 but the last format index was 20
> java.lang.IllegalArgumentException: Text length was 8 but the last format

> ...
So I modified `XSSFRichTextString.getFormatMap()` to sum length after
utf-decoded. Then the test and all tests are passed well.
Actually, I have an original xlsx file that makes this problem, but due to the
security reason, I can't share the file. I think someone can help making MWE.
