There is no need to solve it. When signing a contract, it is valid to sign without normal font. As long as the font signed by the parties can prove that it is signed by the parties. The parties to a contract may sign a contract with their own artistic signatures, minority font signatures or fonts in other languages. According to Article 490 of the General Principles of the Civil Law, if the parties conclude a contract in the form of a contract, the contract is established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it.
