Bug in tag?

[sewix]

In BSPlayer tag {Y:i} is the same as {y:i}...but this tag is different!!!
Tag {y:i} does italics first line. Tag {Y:i} does italics all line.

Example for tag {y:i}:

{444}{494}{y:i}Example text|Example text2

on monitor:

Example text
Example text2

Example for tag {Y:i}:

{444}{494}{Y:i}Example text|Example text2

on monitor:

Example text
Example text2

This bug show else in tag {Y:b} and {Y:u}
