Hi Zhu Zihao, I faced the same problem while working on the Tamil localization. I used the ~* argument jumping supported by (ice-9 format) to work around this. So, for the message "could not find bootstrap binary '~a' for system '~a'", you could do something like "无法找到用于引导 ~1@* 系统的二进制文件 ~0@*" ~0@* refers to the 0th argument, ~1@* refers to the 1th argument, and so on. Look for "argument jumping" in https://www.gnu.org/software/guile/manual/html_node/Formatted-Output.html Hope that helps! Regards, Arun
