recently, I was trying printf debugging, after reading

https://wiki.documentfoundation.org/Development/How_to_debug#Macros_Controlling_Debug_Code

to the following code,

https://opengrok.libreoffice.org/xref/core/sw/source/core/text/itrtxt.cxx?r=f55a9b77#280

I add some lines of code. (I'm too lazy to learn how to use diff command line.)
==================================
if( GetInfo().GetTextFrame()->IsVertLR() ){
    nOfst += rLine.Height() - ( rLine.Height() - nPorHeight ) / 2 - nPorAscent;
}else{
    SAL_INFO("vcl",nOfst);
    nOfst += ( rLine.Height() - nPorHeight ) / 2 + nPorAscent;
    SAL_INFO("vcl",rLine.Height());
    SAL_INFO("vcl",nPorHeight);
    SAL_INFO("vcl",nPorAscent);
    SAL_INFO("vcl",nOfst);
}

break;
==================================
When the line is WITHOUT emphasis mark, the result was:

info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:287: 0
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:289: 401
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:290: 401
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:291: 346
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:292: 346

while WITH emphasis mark on all characters in a line

info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:287: 0
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:289: 499
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:290: 499
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:291: 444
info:vcl:9980:5152:sw/source/core/text/itrtxt.cxx:292: 444
===================================
for the following code

https://opengrok.libreoffice.org/xref/core/sw/source/core/text/itrpaint.cxx?r=180f2860#303

I tried

if ( bAdjustBaseLine ){
    GetInfo().Y( GetInfo().GetPos().Y() + AdjustBaseLine( *m_pCurr, pPor ) );
    SAL_INFO("vcl",GetInfo().Y());
    if ( pPor->Width() && pPor->InTextGrp() )
         pEndTempl = pPor;
    }
}

WITHOUT emphasis mark: 630
WITH emphasis mark: 728.

========================
additional note to my previous post(just to make sure):
I used IPA fonts downloadable from
https://ipafont.ipa.go.jp/old/ipaexfont/download.html for the attachments.
Values here may not be the same when different fonts (with different metrics)
are used.
