Import a range of glyphs from ttf outline font into the current font as symbols, starting from a specific character position. Note: pcb-rnd font symbols are not unicode code poitns, but consists of a single, 8 bit ASCII code page, thus values above 255 are invalid as destination symbol code.

The <arg>srcglyph</arg> argumnet is a single character description or a pair of character descriptions separated with two dots (".."). In the former case the import is a single glyph, in the latter case the import is the whole range between the two characters, inclusive (one or more glyphs).

The <arg>dstchars</arg> argumnet is always a single character description, addressing within the 0..255 range of the pcb-rnd font. This argment determines the first destination symbol that is going to be overwritten. If <arg>srcglyph</arg> specifies multiple characters, <arg>dstchars</arg> is internally stepped after each glyp import, up to 255, where the import stops.

A character description addresses a code point on the input or a character code on the output, using one fo the following syntax variants:

- 'A' is converted to 65 (as a single charatcer using the 8 bit ASCII table)
- is converted as decimal number 10
- is converted as hexadecimal number, to 16
- U+10 is converted as hexadecimal number, to 16
- anything else is taken as a single character and is converted as it was wrapped in ''

The 4th argument is either polygon or line. When it is polygon, the glyph is imported as a polygon (with or without holes). When it is line, all contours of the glyph is imported as a series of lines. When not specified, it defaults to polygon.

Finally, <arg>scale</arg> and <arg>offset</arg> specifies the transformation during the import. Each argument is either a single number or a pair of numbers separated with comma or semicolon or / or * or x, and specify the x and y components of the transformation. When only the x component is specified, y is assumed to be the same (this is useful for scale).
