I use grub4dos as the Bootable CD's boot image.
And I find when when it character set at standard will occur error for me.
First I normaly burn it as standard
then I boot from the cd
it can't find my fontfile unicode.hex.gz & image and I find it in grub environment will be shown as unicode_hex.gz so that it can not be found.
If I change the file name at filesystem and menu.lst as unicode_hex.gz it will all be fine.I
I find the problem because I use command mode instruction binary mkisofs make the same file as iso image and no problem with unicode fontfile and image.
And then I try and find it was about character set standard/DOS/ASCII options
I change character set to DOS or ASCII
then everything work fine Unicode traditional Chinese and image are there
My menu.lst content about this relate are
splashimage=/boot/splash/LRR_640x480.04.gz
font unifont.hex.gz
The problem is if I burn it's character set as Standard then in grub4dos commandline will change to
/boot/splash/LRR_640x480_04.gz
unifont_hex.gz
But in CD's filesystem it
/boot/splash/LRR_640x480.04.gz
unifont.hex.gz
If the filename with more than two dot(.) error will occur.
I don't understand why?and diff about standard/DOS/ASCII and is it bug!?
ImgBurn bug in character set!?

Thank you! Now I got more clear about this issue.So that is not ImgBurn's bug.
I also find the mkisofs and use it to check the different.
Can ImgBurn auto tune the checkbox default status when user switch the radio Standard/DOS/ACII ?
I look at the ISO 9660 Standard and find out this is it's restrictions.
Restrictions
File and directory name restrictions
The standard has three different levels for interchange, here paraphrased from section 10:
The standard also specifies the following name restrictions:[citation needed]
Some CD authoring applications allow the user to use almost any character. While, strictly speaking, this does not conform to the ISO 9660 standard, most operating systems which can read ISO 9660 file systems have no problem with out-of-spec names. However, the names could appear wrong to the user.
