Bug 208921

+++ This bug was initially created as a clone of Bug #206397 +++

Description of problem:
When you type the Hangul, underline appears in preedit.  However it doesn't
appear at the bottom of the letter but 5~10% up from the bottom where I expected
it to appear.

For Hangul, underline in preedit interferes with input since it is one letter
at a time.  Indeed Windows(ime2002) doesn't use underline for Hangul either.

How reproducible:
always

Steps to Reproduce:
1. run gedit and increase the font size
2. activate the scim-hangul
3. type"rnr" <--"극"
  
Actual results:
Preedit has underline towards bottom of preedit which is confusing.

Expected results:
No underline for Hangul.

Well, appearing the underline isn't a bug since scim-hangul uses the preedit.
however rendering it at a character 5~10% upper looks like a Pango or freetype
bug, or font perhaps. reassigning to pango for now.

Attach screenshots please if you can.  And which font is it?  I probably can
reproduce using the font only.

Sorry I can't make screenshots because of pre-editing state.
It is default korean font(Baekmuk), and it is included on FC and RHEL as well

Created an attachment (id=136345)
Typing hangul with scim-hangul, Preedit with Underline on gedit.

This problem doesn't happen in nabi or imhangul.
nabi and imhangul are hangul input method.

preedit of scim-hangul on openoffice writer

The same problem happens on openoffice writer.
So this problem isn't pango bug and scim bug.

So this problem isn't pango bug but scim bug, maybe.

The Main problem is SCIM, becuase Hangul doesn't need a underline.
I discussed with sangu and krisna. krisna said that GTK2 and XIM is using
Underline from SCIM, and he said Hangul doesn't need it.

However, Underline should be fixed in Pango as well.

A patch related to this for gtkimm has been committed upstream:

[Scim-cvs] scim/extras/gtk2_immodule gtkimcontextscim.cpp, 1.170.2.7,	1.170.2.8

This should be fixed now for the scim gtkimm and xim in scim-1.4.4-35.fc6
with patches from upstream cvs.  I will open another bug for scim-bridge.
