Printing Tickets with Unicode codepoints outside basic multilingual plane

[bschmalhofer]

I added the following content to a note:

bes:~/devel/OTOBO/otobo-docker (rel-10_1)$ uni tree
⺦- U+02EA6 - CJK RADICAL SIMPLIFIED HALF TREE TRUNK
⽊- U+02F4A - KANGXI RADICAL TREE
⽙- U+02F59 - KANGXI RADICAL HALF TREE TRUNK
𐂷 - U+100B7 - LINEAR B IDEOGRAM B176 TREE
𐇲 - U+101F2 - PHAISTOS DISC SIGN PLANE TREE
𖢞 - U+1689E - BAMUM LETTER PHASE-C MBAA CABBAGE-TREE
🌲 - U+1F332 - EVERGREEN TREE
🌳 - U+1F333 - DECIDUOUS TREE
🌴 - U+1F334 - PALM TREE
🎄 - U+1F384 - CHRISTMAS TREE
🎋 - U+1F38B - TANABATA TREE
bes:~/devel/OTOBO/otobo-docker (rel-10_1)$

This content looks fine when viewed in the WebGUI. But when printed there are no asian characters and no tree. This is in CustomerTicketPrint and in AgentTicketPrint.

The installation is HEAD of rek-10_1 running under Docker.

Another code point that is not properly printed: 📢 - U+1F4E2 - PUBLIC ADDRESS LOUDSPEAKER
