+ | Here I copy a reply to one user who reported this problem to make it available to others: | ||
+ | |||
+ | <code> | ||
+ | I have had a look at the problem you reported. As I was afraid, it is a | ||
+ | problem caused by different handling of fonts in Tkinter (the library | ||
+ | that BKChem uses to display windows) and Cairo (the library used for PDF | ||
+ | export). These two libraries have separate ways of finding fonts and it | ||
+ | sometimes happens that they find a different one for the same name or | ||
+ | that Cairo cannot find that font at all and uses some replacement. It | ||
+ | can then happen that the font looks slightly different or that some | ||
+ | non-ASCII letters disappear or a replaced by some other strange symbol. | ||
+ | I am sorry but there is not much I can do about it. The only way is to | ||
+ | try to change the font (I was successful with Arial) and re-try the export. | ||
